  1. Heya Kerbonauts, Welcome back to the K.E.R.B.! Bit of a short one today, no major updates to share on the Epic issues - though there's been a good amount of progress on a lot of the issues in the top 20. If you're looking for the news of the day, check out the 1 year anniversary post we just put out. It mentions that the team has squashed over 2441 bugs since launch, with a ton of those being directly resolved because of bug reports sent here on the forums. That's why we truly appreciate your bug reports! See you two weeks! KSP Team Community's Current Top Issues: # Bug Status 1 No trajectory lines in map view Fix being tested 2 Incorrect "landed" status while in orbit causes trajectory to disappear in Map View Reproducible 3 Parts inside fairing heating up Fix implemented and verified 4 Broken DeltaV with multiple engines and/or with side tank attached [fuel tank placement order messes up dV calculations] Fixes being implemented 5 Rovers are hitting a physics glitch every 1000m from the Location of Rover Being Loaded into the Game with Disastrous Results Improved, investigating long-term solutions 6 Timewarp limit is too restrictive on some non-atmospheric planets (Gilly, Bop, Minmus...)

  3. Heya Kerbonauts, Welcome back to the K.E.R.B.! First up, BIG KSP2 NEWS! v0.2.1.0 arrives NEXT TUESDAY (1/30) with heat balance improvements, map UI updates, and many bug fixes! Hope you're excited for that! We think reentry heating definitely feels better and we're looking forward to hearing your thoughts! The table has been updated below on bug progress and some of these fixes are shipping with the patch next week. Don't have many updates past that! One quick note: you'll notice that "SAS does not hold orientation during time warp" is absent from this list. As we've done before, we've decided to remove this one from the K.E.R.B. list to keep things moving, since we don't have any plans to work on this in the short-term. We agree that using time warp and SAS together during long maneuvers is a valuable goal, but this requires additional design and engineering work which is significant enough that it won't be coming soon. We'll share details on progress in this area when there's news. See you next week! KSP Team Community's Current Top Issues: # Bug Status 1 No trajectory lines in map view Partial fix being tested 2 Stage activation requires a double-click / double-spacebar pressing Fix implemented and verified 3 Parts inside fairing heating up Fix being tested 4 Incorrect "landed" status while in orbit causes trajectory to disappear in Map View Reproducible 5 Rovers are hitting a physics glitch every 1000m from the Location of Rover Being Loaded into the Game with Disastrous Results Improved, investigating long-term solutions 6 "Experiment" button shows available experiments even though the experiments have been done before Fix implemented and verified 7 Upper atmospheres heat up and destroy parts far too quickly Fix implemented and verified 8 Timewarp limit is too restrictive on some non-atmospheric planets (Gilly, Bop, Minmus...)

  4. Heya Kerbonauts, Welcome back to another K.E.R.B. report - our first of 2024! We've processed A TON of bug reports from you all from over the holidays and, as you'll see, the top issues have changed dramatically. Some of these were on our radar already prior to the break so the team was quick to jump into working towards some (New Year) resolutions to these issues, while also investigating causes for issues found by you all! v0.2.1.0 is still coming together and we just want to warn that it's possible that some fixes mentioned here may not arrive in time - so they'd slip to v0.2.2.0+. We'll share an ETA with you all once we finalize the release. As always, thank you all for submitting your bug reports - and a massive shoutout to our Bug Hunters as well! KSP Team Community's Current Top Issues: # Bug Status 1 No trajectory lines in map view Partial fix being tested 2 Stage activation requires a double-click / double-spacebar pressing Fix implemented and verified 3 Incorrect "landed" status while in orbit causes trajectory to disappear in Map View Reproducible 4 Parts inside fairing heating up Fix in progress 5 Rovers are hitting a physics glitch every 1000m from the Location of Rover Being Loaded into the Game with Disastrous Results Improved, investigating long-term solutions 6 "Experiment" button shows available experiments even though the experiments have been done before Fix implemented and verified 7 Signals go through planets and moons (CommNet/Antennas not affected by occlusion) The current behavior is how it was designed.

  5. Hey all, FOR SCIENCE! is out and you all seem to be loving it! It's been fantastic seeing the reactions to all the new features, bugfixes, and Discoverables that arrived in the milestone. As we head out the door for the holiday break, we just wanted to do a quick check-in on the K.E.R.B. to take a look at the community's top issues. For those who are just now discovering the K.E.R.B. (Kerbal Endusers Report Bugs!), welcome! This subforum is dedicated to tracking community bug reports and allowing the community to vote on issues that they are also experiencing. This helps the development team prioritize which issues to fix and also get in-depth information to help during investigations. You can submit bug reports to kerb.al/bugreport where they then will be evaluated and categorized by our Bug Hunters. If you're running into issues with For Science!, here's some common solutions: Quicksave, quickload Try a new save file Restart game Remove mods Verify game files Update drivers Reinstall game Thanks again to all of you who submit bug reports. We've seen a tremendous influx of bug reports and it's been extremely helpful during our immediate investigations post-FS! release. Also, yes we have seen Having to eat prevents players from being able to play the game non-stop but you won't see it on this list. We're prioritizing this and have moved it up to the top of our internal bug list. We'll let you know when we have more info to share. Appreciate you all and Happy Holidays, KSP Team Fundamental Feature Status Updates: Upper atmospheres heat up and destroys parts far too quickly (new) We don't consider this really a bug, the heat system just needs some tuning once we can take some time to gather feedback. As we said in the v0.2.0.0 patch notes, do not expect parity between KSP1 and KSP2 in this area! Current Top Issues: # Bug Status 1 No trajectory lines in map view Reproducible 2 Rovers are Hitting a Physics Glitch Every 1000m from the Location of Rover Being Loaded into the Game With Disastrous Results Should have improved with v0.2.0.0, investigating more robust fix 3 Moving a radially attached part with a strut on it, break the game Investigating 4 Stage activation requires a double click / double spacebar pressing Reproducible 5 Landing gear blocked when it is not [also happens with other deployable parts] Unable to reliably reproduce 6 SAS does not hold orientation during time warp Reproducible, investigating alternatives 7 Control Surface Oscillation in Atmosphere Reproducible 8 Inconsistent Framerate During Launch [Edit: The Video Shows a Gradual FPS drop as the Launch Continues] Need to confirm post v0.2.0.0 9 Almost all of the Navball stuff disapears Need to confirm post v0.2.0.0 10 Cannot create/edit a maneuver node when game is paused Reproducible, investigating solutions for this and other pause-related issues 11 "Experiment" button shows available experiments even though the experiments have been done before Reproducible 12 Incorrect "landed" status while in orbit causes trajectory to disappear in Map View and shows landed for the available experiment UI Need more information 13 In "Deorbiting" there is no heatshield in the craft. Investigating 14 More often than not parts are still blocked after fairings are jettisoned Investigating 15 Planets collide after switching vessels Need to confirm post v0.2.0.0 16 Moving a strut reset the camera Investigating 17 FPS drops critically in flight / wing trails in atmosphere are rendered multiple times Investigating 18 Wobbly navball pro/retrograde markers at low relative velocities Investigating 19 Dres's rings always rendering behind the planet Reproducible 20 Game Thinks Entire Craft Is Destroyed Even Though Command Pod Is Still Intact Reproducible Note: this report is not fully representative of the work our team is focused on.

  6. KERBONAUTS, WE HAVE LIFTOFF The time is now - For Science! is now available! We're so excited to release this major content update to everyone. Full release notes for v0.2.0.0 can be found here. We'd love to hear from you about feedback and bug reports on the update - please submit them to the suggestions and bug reports subforums. Dive into and explore For Science! – and don’t forget to share with us your creations, accomplishments, and discoveries. To celebrate the release of For Science!, Kerbal Space Program 2 is 20% off until January 4th, 2024 at 1PM ET. The For Science! update comes with a brand-new campaign type - Exploration Mode, which adds progression and Science collection through missions, experiments, and journeying through the Kerbolar System. Collect and transmit Science from unique locations and redeem it back at the Kerbal Space Center's (KSC) newly opened Research and Development Center to unlock new part technologies, learn novel concepts, and journey further away from the Kerbal's home planet. While working through the tech tree, unlock the means to extend your reach across the Kerbolar System - from right at home on Kerbin, to the furthest regions of Eeloo, and to the murky depths of Eve. Exponential progression ensures that the rewards for your efforts match your ambitions. How will you collect Science? With all new Science collection parts! Integrate these parts to vehicles (be sure to take note of their shape and mass, it matters!) to carry out different experiments, depending on your mission. Keep an eye out for new Kerbal animations when Science gathering during Extra-Vehicular Activity (EVA)! We've overhauled the Science collection and transmission interface for KSP2. During flight, it's now easy to know when there's an opportunity to take measurements or collect samples via a new Experiment Actions button, which provides detailed information about what opportunities are available in your current location. The brand-new Research Inventory gives clear information about how much Science you've already collected and the ability to transmit Science data. The Mission Tracker app helps you keep track of in-progress and completed objectives. New flight planning tools have also been added to the Vehicle Assembly Building (VAB), including altitude and environment-specific readouts that show thrust-to-weight ratio, burn time, and Delta-V for each stage. Data persists and continuously updates in-flight. On your journeys, uncover a wealth of new research locations and mysterious geological formations spread across the Kerbolar System. Locate them and unlock special Science-gathering opportunities - we wonder what you're going to find... The days of stress-free atmospheric re-entry have come to an end with the introduction of atmospheric re-entry heating effects and thermal part behavior. We've also made significant quality of life improvements: An enhanced joint system has been developed, dramatically reducing wobbliness of large vehicles Updated ambient sound systems An all-new Boat Dock - complete with cranes and gantries for use both in-and-out of missions. With this comes additional buoyancy improvements! From us at Intercept Games and Private Division, thank you. We hope you enjoy For Science! and your time amongst the stars!

switching to Mission Control causes the loading screen to hang Workaround: press '>' to resume time Orbit Surveys are difficult to run on small celestial bodies Workaround: geostationary or big elliptical orbits should allow the player to run those experiments. The intention of this part is for it to scan the regions underneath the vessel as it moves over them - however right now it pauses when a new region is encountered, something that occurs a lot when moving fast over some CBs. We are internally testing improvements to this so the part can get its data with less babysitting Miscellaneous text issues in missions, i.e. debrief text repeating Significant amounts of text went into this update, so of course a few things slipped through the cracks. Even if they're minor, please do report them! Separators below a root part will cause improper separation causing loss of control Workaround: Consider using decouplers instead of separators if you are running into this issue Solar panels are sometimes blocked when in Jool's sphere of influence even when Kerbol is in clear view After staring at the sun from Jool's 'surface', black dots may appear and persist even when transitioning back to the KSC Surface-attached lights don't turn on properly when launching for the first time Common Workarounds If you run into an issue, the first thing you should try to save and reloading. We have found many common issues to be quickly fixed using this method. You could additionally try reverting to launch. Performance may degrade over very long play sessions, but restarting the game client should fix this. A Note on Heat It's important to keep in mind that the Part Heat system in KSP2 is different than KSP1, so do not expect parity in this area. Tuning the numbers for the heat system will be a long-term project, so feedback is appreciated!

  8. Curious about what you can expect in KSP2's first milestone update? We chatted with a few key members of the KSP team to give you an early look at For Science!
  9. The team has been hard at work improving the performance of Kerbal Space Program 2 since launch, so we’d like to take a moment to really showcase the difference between the Early Access Launch (0.1.0.0) and the For Science! (0.2.0.0) release coming next week. Here’s a look at some graphs we use to understand the performance of the game and the improvements that have been made to our minimum specification and recommended specification machines: Min Spec Recommended Spec This represents a huge amount of work by the development team across a number of features and releases. With performance optimization being one of the most frequent requests since launch, we're looking forward to hearing from players how this work improves the overall gameplay experience. If you're curious about performance tuning and how we make decisions in that area, the rest of this check-in provides a high-level overview from our Engineering Team and should provide a bit of extra context for the above graphs. Performance 101 As you can see in the charts, performance varies quite a bit between various scenes players might find themselves in. When we’re investigating performance-related issues, we need to investigate many variables both in the game and on the physical machine. Let’s examine the basics of performance tuning and what we look at when trying to make decisions about performance optimization. In keeping with the theme of For Science!, we should start with defining our experiments and the measurements we will use to determine if we are moving in the right direction. So, let’s start with Frames per Second (FPS), which many of you will already be familiar with. A frame is the period required to fully recalculate what has changed in the game state and redraw the scene to the player. The more FPS the smoother the game looks - and feels, as this allows us to capture inputs quicker and update the game state showing those updates to the user in a more responsive way. When we are digging into performance, we want to look at that value in a different way: milliseconds per frame (ms). Why would we do that? Basically, we want to understand what, in a given frame, is taking up time so we can make it faster. For a 30 FPS goal, we get 33.3 milliseconds per frame, so it becomes a lot easier to set a budget for how much time a given section of the game should take. But what are we taking time from exactly? There are two pieces of hardware we generally are looking at for performance: the GPU and the CPU. At a high level, a Graphics Processing Unit (GPU) is a piece of hardware that specializes in the types of calculations that are needed to render a given scene. It is much faster at smaller tasks in parallel than a Central Processing Unit (CPU) but much slower at running tasks in a series. In order to get the maximum performance out of a computer, we want to use both to their full potential and optimize the game accordingly. Now some of you are thinking “What about memory, storage devices or things like that?” And you’re right that we do consider those things, but for the purposes of this overview we are going to concentrate on the biggest items that affect performance. But bonus points all around. An example internal debug output One of the important parts of performance tuning is to understand what the bottleneck is in each scene, either the CPU or the GPU. In the image above the CPU is taking 44ms per frame on a scene and the GPU is only taking 19ms. The CPU is the bottleneck in this case, so it doesn’t matter how much more optimization we do on the GPU. To improve this specific case on this specific hardware, we need to determine and target the most expensive operations on the CPU. One of the challenges of making a PC game compared to consoles is the variety of hardware choices, specifically when it comes to CPUs and GPUs. There are thousands of combinations that someone could have, and each of them is going to perform slightly differently. That doesn’t even get into memory differences or software differences like operating system patches, hardware drivers, etc. This is why we publish minimum and recommended machine specifications - to help players understand what we have tested and if their machine should be able to play the game with adequate performance. Now that we have some background on what developers look at for performance tuning, let’s go back up to those graphs at the top. For one, these are per-configuration graphs, which are used to tell us how the game is performing on that specific hardware. We do lots of these which help us to remove the hardware variables from the tests and just look at how the given build is performing overall. It also lets us look at this data over time and see if things are improving or not. As we add features, these will always affect performance, so we need to be checking the deltas consistently to determine where we need to spend time on improvements. The other thing these graphs help determine is if a given hardware setup has abnormal issues compared to other similar setups. A given manufacturer may have optimized their hardware in such a way that we get different performance out of certain improvements and knowing that helps us optimize the game for the entirety of our player-base across a wide range of hardware options. --- We hope that this has been informative! As we work towards larger performance optimization goals in the future, we’ll be sure to share updates in posts just like this – and perhaps take a more technical deep-dive in performance-focused dev blogs, so let us know if you’d like to see that! Thanks for reading and hope you enjoy For Science! KSP Team
  10. Hello Kerbonauts. I'm Ghassen, also known as 'blackrack,' the newest graphics programmer on the team. You have no doubt noticed that we have improved the atmosphere rendering in 0.1.5.0. Today I’m going to share with you some insights into those improvements, as well as some of the improvements that are going to be in 0.2.0.0. Inspecting the atmosphere: This is how our atmosphere appeared in 0.1.4.0 on Kerbin: We can see a very nice-looking sky. However, the effect is very subdued on the terrain, we have trouble reading the terrain topography: It is difficult to tell what we are looking at in the distance and the sense of scale escapes us. Are those mountains? Are those hills? Cut to 0.1.5.0 we can immediately see a big improvement in the scene’s readability: We can now immediately get a sense of how far away things are and we get a better sense of scale. This is what’s known as aerial perspective. How the atmosphere is rendered: We are using a precomputed atmospheric scattering method which is standard nowadays in computer graphics, and popularized by Eric Bruneton. It is precomputed meaning all the heavy calculations involved in simulating how light scatters through the atmosphere are done once, for all possible altitudes and sun angles, and then stored in compact and easy to access tables. The latitude and longitude of the observer on the planet does not matter because we can use symmetries and effectively just change the altitude and sun angles to get the scattering at any viewpoint. These tables can then be used to display the effect in a very performance friendly manner when the game is running. These are known as look-up tables. This what some of the slices in our look up tables look like: How aerial perspective is rendered: The look-up tables I’ve described earlier can be used to find the colour of the sky for any given viewpoint inside or outside the atmosphere, as well as how much the atmosphere occludes celestial objects behind it (this is known as transmittance or also extinction, it describes how much of the original object’s light is transmitted and makes it to the observer). The look-up tables only allow us to get the light scattered towards us from the edge of the atmosphere, and assume we are always looking towards the edge of the atmosphere, so we cannot use it to directly to get the colour of the atmosphere up to an object. This is because the look-up tables would otherwise become impractically big and would eat up our memory budget. However, since the look-up tables allow us to get the colour of the sky from any viewpoint, we can re-express the scattered light up to a point/object as the difference between two samples to the edge of the atmosphere, starting from different positions. We also must apply transmittance to the observer to second sample (in red on the diagram) for everything to be correct. Putting it in-game: So now that we know the method to render aerial perspective, we can plug it in-game, and see what we get. Behold: Hmm that looks really strange around the horizon, so what’s happening here? Recall that we are using look-up tables, these are loaded on the graphics card as textures, and they have limited resolution and precision (bit depth). The aerial perspective method described earlier only makes precision issues worse by taking the difference between 2 samples, especially on high variance areas (typically around the horizon) where any imprecisions are amplified. The way to deal with this is to first inspect the look-up tables, see if anything is stored in low precision textures or with any lossy compression, and use high precision instead where needed typically (16-bit and 32-bit per channel floating point textures). After that, we can then change the parametrization for how samples are distributed across the look-up table to maximize resolution where it is needed. The original paper offers a nice way to distribute samples, but we found that it works best for physical settings matching those of Earth, but not for some of the settings used at Kerbal scale. Finally, we review all the lossy transformations in the math and try to minimize any loss of precision and guard against various edge cases. This is where most of the engineering effort in implementing precomputed atmospheric scattering is spent. Right now we have gotten our implementation to a good place, however the inherent limitations of the method means that in the future we will move to a different, non-precomputed method which doesn’t suffer from these issues and would allow us greater flexibility. The importance of mie scattering: We simulate Rayleigh scattering (air particles), mie scattering (water droplets and aerosols) and ozone absorption, each of these is important to represent a different effect and render all the kinds of atmospheres we want. Mie scattering has a particularly noticeable effect and can be used to make atmospheres look foggy and cinematic, all the while keeping a realistic look. I took these screenshots early in testing the atmosphere changes to illustrate the difference increasing mie scattering makes to a scene: In the end we went with a relatively subdued setting on Kerbin and a nice heavy setting on Laythe to set them apart, also as a reward for flying to Laythe. Atmosphere as Lighting Recall that we have the transmittance that we discussed earlier as the part of light that reaches the observer and objects in the atmosphere. We can now use that to light objects, by applying it to sunlight, this gives us the very nice and soft lighting you can see around sunsets and sunrises: We can also use the transmittance on the clouds, notice how areas in direct light can get a nice reddish color, while areas not in direct light get ambient light, and we get a very nice contrast between the reddish transmittance and the faint bluish ambient: Using the atmosphere to do lighting also simplifies artists workflow, as the alternative was to try and approximate the different lighting parameters at different times of the day via various settings and it was very difficult to make the clouds look “right” at every time of day. Now we have less work to do and it looks better and more coherent. Speaking of clouds, next we will discuss of some of the performance improvements coming in 0.2.0.0, but first let’s see how clouds are rendered in more detail. How clouds are rendered: Modern clouds are rendered via raymarching, a technique that involves “walking” through a 3D volume, incrementally sampling properties like density and color as we move along, and performing lighting calculations. This method provides a more accurate and visually appealing result compared to traditional rendering techniques and is very well adapted to rendering transparencies and volumetric effects. This figure shows in red all the samples we have to do for a single ray/pixel on-screen: Because of the number of samples we must take during the raymarching process, it is very demanding performance-wise. A solution to this it to render at low resolutions and upscale. Temporal upscaling: Temporal upscaling was introduced in 0.1.5, the idea is to render a different subset of the pixels every frame. This is similar to checkerboard rendering if you’re familiar with the concept but generalized and not locked to half resolution rendering. This diagram shows how 4x temporal upscaling works, a full resolution image is reconstructed over 4 frames: In movement, the old pixels are moved to where they should be on the current frame, based on their position in space and how much the camera moved from the last frame, this is called reprojection. After moving the old pixels, their colour is validated against neighbouring new pixels, to minimize temporal artifacts, this is called neighbourhood clipping and is the foundation of modern temporal techniques like TAA. Despite the neighbourhood clipping, we were still getting artifacts and issues after this stage in motion, due to the high number of “old” pixels compared to “new” pixels, typically this manifests itself as smearing or flickering. Our solution was to re-render the problematic areas separately at normal resolution, since these areas are only a small part of the final image. This sounds great in theory, but while flying around clouds in a fairly heavy scenario we can see the following timings on a 2080 super at 1440p: Low-resolution rendering of new pixels: 5.45 ms Reproject old pixels and assemble full resolution image: 0.12 ms Re-rendering of problem areas: 4.11 ms Process and add clouds to the rest of the image: 0.09 ms For perspective, if we want to reach 60 fps we need to render in ~16.6 ms, so this step seems to take a sizable chunk of rendering time in 0.1.5.0, even though we are rendering faster than we did in 0.1.4 using this approach. This is because those re-rendered areas are at the edges of clouds where rays must travel furthest and evaluate the most samples before becoming opaque or reaching the boundary of the layer. For 0.2.0.0 we took a bit more inspiration from temporal techniques to find an alternative solution to re-rendering problem areas: If colour-based neighbourhood clipping isn’t sufficient, we can use depth and motion information like speed and direction of movement (on-screen) to try and identify when reprojected pixels don’t belong to the same cloud surface/area and invalidate them as needed. The idea is to store all this information from the previous frame, and every frame we do a comparison with the previous one to get a probability that a reprojected pixel/colour does not belong to the same surface we are currently rendering. After some implementation and tweaking this ended up working well and we can see the following improvement in rendering performance (screenshots taken on a 2080 super at 1440p, framerate counter in top left): On the launchpad we went from 77 to 91 fps In flight around the cloud layer we went from 54 to 71 fps That’s about a 17-31% performance improvement on the whole frame and we save 2 ms to 4 ms on the rendering of the clouds. You can look forward to these performance improvements and more in 0.2.0.0!

  13. Heya Kerbonauts and welcome back to the K.E.R.B! After the doozy of the last K.E.R.B. update, we have somewhat of a shorter post today. v0.1.5 has been out for two weeks and we've seen so much more engagement with the K.E.R.B. this update than ever before. As always, thank you so much for reporting and upvoting bugs - it truly helps the future development of KSP2 Last week we shared a major change to the K.E.R.B.: removing entries that require fundamental feature overhauls. You can read more about the justification for that change in the last update, but one of the things we did commit to was to provide insight on the issues that we remove from the list when we have notable updates. Thus: Wobbly Rockets: Improvements have been fully implemented (see the video in the last update) and are ready to ship for For Science! Calculating Physics of all parts of all Crafts: Improvements are fully implemented and are ready to ship for For Science! Surface Rendering Fragment Shaders are Inefficient: We believe this requires some reevaluation by fans post v0.1.5 as we implemented mesh bucketing for terrain which should have significantly impacted the original issues. Camera Resets Position Map View: Has been "upgraded" to this list as it and many other camera issues are planned to be addressed in future camera systems work, scheduled for post-For Science! And now to the list: Current Top Issues: # Bug Status 1 No trajectory lines in map view Unable to repeatedly reproduce, need more information 2 Phantom forces when deploying landing legs/gear Reproducible 3 Rovers are Hitting a Physics Glitch Every 1000m from the Location of Rover Being Loaded into the Game With Disastrous Results Reproducible 4 Black visual artefacts when passing through cloud layer (AMD) Fixed, needs verification 5 Moving a radially attached part with a strut on it, break the game Two separate issues, one with struts, one with symmetry.

This is just to provide insight into our progress on the most concerning issues to our community. Additionally, the lack of a status update does not imply a lack of importance or general progress - we just do not have anything to share at this time. Lastly, we've opened up a K.E.R.B. feedback mega-thread so if you have any suggestions, please let us know. We're planning for some pretty significant changes to the K.E.R.B. post-For Science! and, as this is a collaborative effort between the community and the dev team, we want to make sure you all have a voice in the way we approach bug reports moving forward. Appreciate it! KSP Team
