Kerbal Space Program 1.9: "There’s No Place Like Home” Grand Discussion Thread


Recommended Posts

P_EcWFM3aHJYmSC6MCc7U3B57VNxntfa_2-c0HOJ

Hello everyone!

Kerbalkind has been exploring the vastness of the Kerbolar System for many years: they’ve explored the surfaces of planets and moons, encountered beautiful landscapes, interesting surface features, performed experiments, and even captured asteroids, all with ingenuity… and many explosions. However, sometimes it’s good to look back and appreciate the wonders of your own home-planet and realize that There’s No Place Like Home!

Kerbal Space Program 1.9: There’s No Place Like Home draws its name from the substantial graphical overhaul we’ve given to Kerbin with improved textures and shaders, but that’s far from the only thing you’ll find in this update. Mainly focusing on performance improvements and bug fixes, 1.9 also includes some neat part revamps, a brand new drain valve, and several additions drawn directly from your feedback. Additionally, we’re including some cool stock crafts for the expansions, and advanced control improvements to the blades in the Breaking Ground Expansion.

Let’s go through some of the update’s highlights below:

Visual Revamps for Moho Dres and Kerbin

Kerbin, Moho and Dres have received major visual improvements, with detailed high-quality texture maps. Since there’s no place like home, Kerbin  also includes an Ultra Quality shader option for exceptionally sharp visuals. All in all, the Celestial Bodies in the Kerbolar System are looking better than ever.

Drain Valve

Kerbal Space Program 1.9: There’s No Place Like Home features the FTE-1 Drain Valve. A brand new part that, as the name suggests, is a release valve for parts with drainable resources, such as monopropellant, ore, liquid fuel, oxidizer or xenon. The Drain Valve also allows you to set the drainage over a specific amount of time.

Part Revamps

The "Thumper" Solid Fuel Booster, "Mainsail" and “Skipper" Liquid Fuel Engines have been given a new look. New geometry, textures and emissive maps make these parts look sharp and realistic. On top of that, the "Mainsail" and “Skipper" are getting a couple of sleek variants for you to choose from.

Quality of Life Features

Drawing from our players’ feedback, Kerbal Space Program 1.9: There’s No Place Like Home is packed with some useful quality of life features like an adjustment to the time warp system that removes restrictions on warping at certain altitudes; a new cheat menu option that allows you to place your craft above the surface of any celestial body; a search box for the R&D Tech Tree; and a new Screenshot Mode for paused shots, and several others! 

Blade improvements 

Breaking Ground players can now enjoy cyclic & collective deflection controls to the blade parts. This will help you build and pilot helicopters and other rotorcraft realistically. Check out this devblog to learn more about it.

As with every release this thread will be used to bundle all general discussion about the new version so that the forums can continue to actively host threads on other topics as well. CLICK HERE for the official release announcement for Kerbal Space Program 1.9: There's No Place Like Home.

Happy launchings!

Huh, figures that 1.9 would hit literally hours after I finally update my mods to 1.8.

 

Really looking forward to the cyclic/collective changes to rotor blades.  Trying to implement a functional swashplate system without massive part-count was... not going well (rather, it went nowhere).

Minimum mass/minimum cost definitions in config files and validating the mass and cost values to not be negative is a fairly useful (but bug-hiding) feature.  IN theory it shouldn't be needed if parts and mod code works properly, but at least now when it isn't working, things won't start flying off into space on their own (negative mass on a craft does weird things).

Add new Cheat option in the Debug Menu  - Set Position to teleport a vessel to a position relative to the surface of a celestial body.

^^ Is simply a wonderful addition to the stock debug tools, that has been missing ever since they added the object relocation functions.

Would it be possible to get a little technical background/information of this improvement?

I just might give playing completely (or nearly) Stock a try with the latest update. See what it's like while we wait for the mod updates. 

All my mods are working fine so far.

I too would like a bit of additional info on that.  Missed it during my brief peruse of the patch notes.

Knowing a bit about the internals of how KSP renders things, I would imagine that this means they are no longer compositing the final viewed image from multiple cameras (near/local, and far/scenery/celestial objects).  If true, this would go a long ways towards cleaning up rendering issues regarding reflections and other post-processing effects (e.g. scatterer).  Single camera, single transform matrix, single render texture/render-target.

The improvements to performance likely won't be anything crazy, but it is a great step towards simplifying the rendering.

Wondering what in the recent Unity versions allows them to do this, or if it was other changes to the rendering code?  I've spent some time myself trying to solve that issue for personal game-dev projects, and the dual-camera setup is the only solution that I could reliably get working while keeping things 'simple'.  Perhaps they've gone from a 16/24-bit z-buffer to 32 and implemented logarithmic depth calculation?  Those changes combined might be enough to give good enough precision for only a single camera (though I thought logarithmic depth buffers had been in use for many years as a standard).

Was this the point where they switched to using a reverse-float (log) depth buffer?

I remember that becoming available in Unity earlier (and Blackrack pointing out the advantages thereof) but wasn't sure if it was in-game already

To quote blackrack >

Graphics: Improve shadows precision for large game worlds. Use reverse-float depth buffer for improved depth buffer precision on modern GPUs. Particularly improves directional light shadowing for large view distances.

Using this and a logarithmic depth buffer, this would allow squad (or me) to merge the near and far cameras into a single camera, using a unified depth buffer. This would simplify otherwise impossible or too complicated effects due to splitting of the scene on multiple cameras and multiple depth buffers, including screen-space reflections, refraction (ocean or heat/particles), ambient occlusion, depth of field and many more...

Right now I've already figured out how to make all the game shaders write logarithmic depth, and using just one camera it works beautifully, except for the shadows which suffer from precision issues, and not just a few artifacts here and there, I'm talking shadows getting down to the boogie and flickering on every surface.

This would indeed "unlock" several cool graphical effects, like really cool effects, I'm not sure however what the overhead is for migrating from the current version to 5.5 and I see why it's not a priority. It would be amazing though, one can dream.

 

I have bolded the bit which I am suspecting has come to pass?

So...

* Blades auto-detect cyclic vs collective control mode based on location of rotation axis relative to the vessel center of mass, per control axis. Mode indicated in Rotation Control State group in Advanced Tweakables.

Is this available for more than just blades?  Outboard jet or rocket engines for instance?

No. Sorry. Only ModuleControlSurface.

"Fixed audio fade with camera distance" Thank... God. That is the best thing for me in 1.9. The engine audio not fading with distance was killing this game for me.

As this feature is simulating collective pitch, as utilized by helicopters and other rotorcraft, I'm not sure how it could be applied (conceptually) to combustion based engines.  Those engines can't really put out more thrust on one side of the engine than the other; there is only one nozzle, which determines the direction of thrust.

Rocket engines/etc can already do vectored thrust with the use of the gimbal module; different concept and applications, but is how thrust is controlled on those types of engines IRL.

Many thanks for the info, seems to be exactly what I was looking for :)
