It has been a while since I wanted to this, but finally, I took the time ^^ Information on KSP IVA modding tend to be scarse, or old, so this is an attempt at making a centralized place for that, with all my experience and others's I could find, put together : https://github.com/kurgut/KSP-IVA-modding-Guide/wiki I choose to put this guide in a github Wiki, so it can be a centralized place, where people can contribute, suggest modifications. This is also much more "readable", organized, and easier to modify than the forum post format. So feel free to use this place here as a discussion thread, for questions, or if you want to suggest changes and / or additions to the wiki : ) For that, you can also use the Discussions section of the repo > Wiki-feedback channel For now the wiki includes : - Unity editor setup for KSP - Modifying existing IVAs - Useful links and resources To add, complete : - Creating your own IVA wiki page : Modeling blender setup .mu Internal space orientation VS parts layers apply scale clear inverse materials / textures / KSP/shaders import/export MbD internals props related internal modules related part modules cfgs and mod folder structure MM RPM MAS FreeIVA Reviva Props Debugging Others My KSP discord server you can join too, if you have questions, it's mostly filled with IVA nerds : P https://discord.gg/GcfDk4DYHU Credits : Some part of the writing in the guide comes from @Poppa Wheelie really good post on Unity setup : https://forum.kerbalspaceprogram.com/topic/226382-unity-setup-guide-for-iva-editing-2024/ Happy IVA modding !

KSP IVA Editor Station SETUP To create a functioning workstation for editing KSP IVA's and props, follow this installation manual EXACTLY and everything WILL WORK. STEP 1: DOWNLOADS Download the following files from the internet. Names and versions are PRECISE. a) Unity Hub - Install current version from website, register and login. b) Unity (Main Editor Program) "Unity 2019.4.18f1" c) PartTools_AssetBundles_2019.4.18f1 d) TextMesh Pro Release 1.0.56 - Unity 2017.3 e) ImageMagick - download installer from website STEP 2: INSTALLATION If all pre-requisite software has been downloaded, begin with installation of the main UNITY program. Confirm installation success and note installation path. Next, open UNITY HUB and select "INSTALLS" from left Menu. Select "LOCATE", and show "UNITY HUB" where you installed the main UNITY program. "2019.4.18f1" should now show on the list. Now navigate back to the "Projects" menu. Select "New Project" button, and select "3D Core". Give your project a name under "Project Name", and select "Create Project". Unity will now launch. Minimize Unity, and launch "ImageMagick" installer. Upon completion, close "ImageMagick" if running and return to Unity window. STEP 3: Modding UNITY With the UNITY window open, select "Window" from menu bar, and select "Package Manager". Scroll down the list and find "TextMeshPro", highlight it and select the "remove" option. This gets rid of the version you DO NOT need. Allow un-installation to finish and close "Package Manager" window. Now select "Assets" from menu bar, and select "Import Package > Custom Package". Select your download of "TextMesh Pro Release 1.0.56 - Unity 2017.3". When extracted it will be a "Unity Package File". Click OPEN. Now an "Import Unity Package" window will open. Make sure everything is selected and hit "Import". Now select "Assets" from the menu bar again and select "Import Package > Custom Package" again. After the "Import Unity Package" window opens, select your "PartTools" download after extraction, and once again check that all boxes are checked and hit "Import". Now you will see a new entry on the menu bar called "KSPAssets". Now on the bottom navigation window, make your way to the following path: Assets > Plugins > KSPAssets. Check that BOTH "KSPAssetCompiler.dll" and "KSPAssets.dll" have the checkbox "Validate References" UNchecked. To check, highlight the .dll and look at the info that shows up on the right menu panel. "Inspector". (WITHIN UNITY) CLOSE UNITY. OK now you're done setting up the tool. STEP 4: Setting up your KSP content. Install a fresh copy of KSP In a folder of your choice just note the installation directory. Within THAT particular installation of KSP, now add any mods required if the target you are trying to edit is part of a mod pack. Dont worry about mod pre-requisites for functionality, just put the mod that contains the IVA and PROPS you want. This will be your "UnTouched" GAMEDATA folder. Now create a new folder somewhere you can find it, this will be your "Modded" GAMEDATA folder, and copy the GAMEDATA folder into your new "Modded" folder. After this point only work in/on the "Modded" GAMEDATA folder. Carefully go through the stock and mod folders and trim as much as you can. Most things can be deleted except the "Spaces" and "Props" folder. Just keep in mind the IVA you want to modify has to BE there. AND all the stuff you want to use prop wise has to still be there as well. When done trimming, return to the root of your "Modded" GAMEDATA folder in file explorer. In the file explorer address bar type CMD to get a command prompt window to show up within GAMEDATA. Copy and paste the following command. (assuming you DID IN FACT install ImageMagick as instructed) FOR /R %f IN (*.dds) DO mogrify -verbose -flip -format png "%f" Now the textures of all things you are about to work on will show up in Unity. All your content is now setup to work. Open Unity Hub and you should now see your project listed by name. Open your project and select from the Unity Menu Bar, "Tools > KSP Part Tools". Drag and drop the "Part Tools" window over to the right beside "Inspector". (common usual location for it) Now click "Set Data Dir" and select your "Modded" KSP GAMEDATA folder. You should now see two menu columns labelled "Spaces" and "Props" populate. INSTALLATION COMPLETE Tested in 2022 on KSP 1.12.2 Now you can spawn any IVA or prop and re-decorate it to your hearts content! Have fun!

I'm working on IVA's in unity but have been unable to find a way to search or sort the Prop spawning list in part tools. There are hundreds of props that are not ordered alphabetically and the control+f search function does not work in this window. Does anyone know how to either sort or search through the prop list in part tools? I've read every IVA tutorial on these forums and spent several hours now searching on several search engines using many different phrases and combinations of quoted and excluded words and cannot find anything related to this window. Below is a picture of the window I am talking about. Any help would be much appreciated.

UnityPlayer.dll caused an Access Violation (0xc0000005) in module UnityPlayer.dll at 0033:9679ba80. This is the crash report error that's been ruining my games all this month of November and part of December, ever since I built this new PC. New motherboard, new CPU, new GPU, new SSD, old RAM though. This are my PC specs: CPU: AMD Ryzan 7 5800X 8-Core Processor 8/16 0,0v Motherboard: Gigabyte Technology Co., Ltd. B550 AORUS ELITE V2 RAM: 16GB GPU: NVIDIA GeForce RTX 4070 Ti (12,0 GB) Windows 11 Pro I use a lot of mods, but that wasn't a problem in my old PC. Of course, I would get a crash after hours of gameplay but that wasn't a hustle, this is, and it's very annoying and game breaking. Please, I need your help. First things first, here are all the logs: CRASH LOGS This is my mod list (Most of them are dependencies and many others have proven to be compatible & required mods through The Skyhawk Mod Support List), I will list which of them are part of that list in the following one with . I will use for dependencies and for visual and scale mods. I will also mark the ones I have just because I want to have them with : Only 75 emojis allowed, continuing in the next post below:

Hi, I'm new to unity and modelling in general, my wish is to modify an existing modded IVA for personnal use. I was adviced I needed KSPparttools for that (aalthough, I'm not sure ? since I'm not creating an actual part ?) So anayway, I followed JPLRepo post and instructions : Download Unity 2019.4.18f1 and run it. Then open your Mod project, upgrade it to Unity 2019.4.18f1. Uninstall the built-in Unity TMPro package from Unity 2019.4.18f1 - Go to Window - Package Manager in Unity and Select TMPro and uninstall it. Download this exact file "TextMesh Pro Release 1.0.56 - Unity 2017.3 " from https://forum.unity.com/threads/useful-information-download-links.458634/#post-3304434 and import it into your Mod project in Unity using Assets - Import Package, Custom Package menu option. Import the custom bundle in the zip file above into your Unity project. Disable "Validate References" for the KSPAssedCompiler.dll and KSPAssets.dll in the "Assets/Plugins/KSPAssets" folder. Restart Unity and reopen your mod project. That's ALL you have to do. Currently I'm stuck at "Disable "Validate References" for the KSPAssedCompiler.dll and " etc. As I don't know where this folder is, and how to access it and disable the said thing. Also, if you do have general tips to get started with IVA modelling/modifications, I'd be happy to take them ! Thanks a lot Cheers

Hi , For last two days I tried to create a KSPedia JNSQ delta map chart, but I can't get past the problems with missing TextMesh Pro Release 1.0.56 - Unity 2017.3 link. Please if someone has a free version of TMPro available and could kindly share, I would be very gratefull Edit: after doing some research I have found that 1.0.26 TextMesh Pro is the same as 1.0.56 as described here in Unity Docs . Also I have found a way to obtain package 1.0.26 from Unity package manager by dynamically editing package.json in project files. What I can't figure is how to make the ksp part tools recognize the Text mesh pro as the required 1.0.56 instead of 1.0.26. Anyone could help or help me at least take a direction?

How do I load in a prefab into KSP? My prefab(s) are smoke particle effects that I would like to instantiate in code, and they are created in the Unity Editor. How do I export them into a format KSP recognizes and load them via code?

I think the KSP2 team was waiting for the 2021 LTS release for Unity so they can lock features into a stable product. Now we can expect some very cool features in the game related to environments and like it was designed with KSP in mind (I wonder if there was some collab between Intercept and Unity): "HDRP performance upgrades and features like NVIDIA DLSS for desktop, Volumetric Clouds, and Static Shadow Caster." I've seen some pre-LTS environment videos, everything looks absolutely amazing. Some of them even show storms with wind, rain, lightning and snow. There's also Expanse with some impressive demos, I don't know if the KSP2 uses this or their own tools. Wonder if we'll also have Ray Tracing..

Ok, so I grabbed ASET props to put together a custom IVA for the new MK1 pod, but I cant find any unity files or tutorials on the subject. Could someone nudge me towards the answer?

Hello! I am currently trying to make my own mod for KSP, allready done the modeling, texturing and all the stuff. I imported the blender file into Unity and succeed to have the main texture and the normal map imported. But I do not succeed to import a roughness/smoothness map and a metallic map. I read that I have to make a RGBA file with the metalic in R, normal in G and smooth in A. If it is that, how can I do so? Thanks in advance!

Hi all, I am very new to add-on development, and I was wondering why part attach nodes are written in the CFG if they're configured in Unity along with the materials, CoM etc. (photo of node lines in the CFG) Also, a little side question, does anyone know of any good tutorials for developing parts? The one on the KSP wiki is quite outdated.

So, sometimes the game freeze and the last lines of the KSP.log are: [WRN 16:25:46.084] Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak [WRN 16:25:46.084] To Debug, enable the define: TLA_DEBUG_STACK_LEAK in ThreadsafeLinearAllocator.cpp. This will output the callstacks of the leaked allocations Any idea of what is this and how to avoid it?

Hi, I've been encountering an annoying unity crash when playing. It's not easily reproduced (unfortunately), seems to happen more often in the VAB than anywhere else, but it also occurs in flight - so far never in the tracking station or any other scenes. With high part / large craft it occurs more often, but it also occurs if I play KSP for more than a couple of hours at a time without restarting it. Unfortunately the KSP log file is not helpful when this occurs - it simply outputs the last "in game" event and then nothing. It's a Unity crash (the Unity window pops up and it's trying to generate a crash report), so I'm not convinced that it's something in the mods I'm using. I've put the Player-prev.log (from C:\Users\<name>\AppData\LocalLow\Squad\Kerbal Space Program) above in a spoiler that shows everything after the crash occurs. This is outside of my technical comfort zone, can anyone offer any assistance please?

Hey yall, What are some good resources to learn how to make animated parts?

Hi, when I launch KSP with Steam, it shows me this window and crash. https://imgur.com/a/fUwmEvv EDIT: I don't have any mods and if I run KSP_64.exe it shows me a same error EDIT 2: I tried to reinstall game - same problem

As the title says, whenever I've tried to launch any version of KSP from 1.8 up the game immediately crashes; the screen goes black and the cursor changes to its in-game appearance for about a second, but then the Unity crash handler throws up an error window: and the application closes itself. I've had this issue for months now, and it started occurring with a copy I'd already been using for some time but has persisted throughout the numerous times I've tried to use fresh installations. As I wrote this, I downloaded portable copies of 1.8.1, 1.9.1, and 1.10.1 from KSP's website (because I tended to use the installer and frankly I'm grasping at straws) to make sure they still weren't working, and they all failed in exactly the way I described. For the record, there was no crash log or anything, and while normal logs have (I think) been created they're pretty much empty, only showing very basic information about my system and the application. My computer's specifications (copied from that log) are: OS: Windows 10 (10.0.0) 64bit CPU: Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz (8) RAM: 8079 GPU: Intel(R) UHD Graphics 620 (2147MB) SM: 50 (Direct3D 11.0 [level 11.1]) I've tried to solve this problem before, and it's clear that there are other people that have had this problem, but to be honest I don't understand what the solution is or if there even is one. From what I've gathered I think it has to do with my graphics driver, but if that's the case I don't know what I'd have to do exactly to resolve the issue. I've tried updating the driver, at least, but that didn't do anything; I'm thinking I might have to just trial-and-error my way through older drivers until I find the one that worked. I've managed with keeping the game at 1.7.3 for now, but it'd be nice if I didn't have to.

The link to my log is here. (Note: I also play 1.3.1, it is affected.) Mods: RPM 0.31.1 De_Iva extension 1.0.2 ASET props Toolbar Controller

Hey, I'm having some issues making a docking port; I have the whole docking thing worked out (finally), but I can't figure out how to make them detach when they're already put together in the VAB. I'm pretty sure it's the same mechanism as a decoupler, but I can't find any (working) documentation on it. So... anyone know what to do?

Hi folks, I have a curious issue that has reared it's ugly Kerbal Krashing head a few times so I'm wondering if any of you fine Kerbalnauts have had (or fixed) the same problem. I can't recall specifics from any previous times it happened but on this occasion, I had reached space (in a ship with 30 parts - started a new career save) and separated down to my final stage all without issue. I then went EVA to do a report, but when I boarded my capsule once again and adjusted to a retrograde profile, the program seemed to erm… 'half-crash'. My vessel became unresponsive and figured the battery in my capsule had died so my reaction wheels were unable to counter my turn to retrograde and thus continued spinning on the axis I turned. Alas, the battery was still 75% charged. I tried some other controls, beginning with another EVA which worked but I couldn't board the vessel again, I could look at the messages, contracts, deltaV info etc, I could minimize the navball and bring it back upt yet I could still not enter my craft or get it to respond in any fashion, then I also noticed I could no longer move the camera - but still I could do the other things. I brought up my task manager to see if it has stopped responding but according to that it was still fine. Then I noticed a 2nd program running under the KSP heading - this was the UnityCrashHandler64.exe - THIS file was listed as not responding. I am using the latest 64 bit version of KSP - recently purchased on the COVID cheap through steam with both expansions on a nearly new Intel i5 MSI gaming laptop and apart from a little occasional stuttering, it runs perfectly 99% of the time. I can only confirm this as unity crash for this specific crash but I believe it has been the same crash previously (3 or 4 times) - each time the only ting I can do is end the task on KSP and restart the application. I would be extremely grateful if anyone has a solution to this issue, Thanks Kerbalnaut #55487 --- EDIT --- I could find no output.log file in my KSP folder but I did find a KSP.log file, the last entries were - [LOG 17:50:36.075] [Experiments]: FX Modules set: 0 [LOG 17:50:36.079] [FLIGHT GLOBALS]: Switching To Vessel Untitled Space Craft ---------------------- [LOG 17:50:36.079] [PlanetariumCamera]: Focus: Untitled Space Craft [LOG 17:50:36.090] Camera Mode: AUTO [LOG 17:50:39.835] [Experiments]: Setting FX Modules to 1...

Memory Mapped Files The closest example to this technique is kRPC, which I experimented with about a year ago when developing my F-22 drone racer. I discovered there was a significant delay between the server and client however. I was drawing a Vector3 representation every frame at my vessels position, which would fall further and further behind the craft as it's velocity increased. I have used Unity's uNet client and local server and have not experienced this lag before, which has me stumped on the cause. I would be interested to chat with someone who knows more about this mod, or anyone who has also experienced this. Because of the lag I was experiencing with kRPC, I decided to build my own "bridge" using Memory Mapped Files. These allow multiple processes to share memory space, which can be used to store several different types of data structures. While these are easily the fastest way to send data, there is one major complication for this project. Mmap files are only supported in .net 4+, while KSP targets 3.5. My solution to this is to start a custom process at launch, which handles the memory map "bridge", then I send/receive values via the process's i/o stream. This allows me to send hundreds of values back and forth each frame, at 50+ ksp fps, which is perfect for the time being. My next goal however is to send much larger data structures over the bridge. I really want to get camera feeds from KSP into Unity, so that I can begin implementing VR control into my mods. I have successfully sent a Texture 2D byte array from a camera across the bridge on a frame-by-frame basis, but the problem is when I need to incorporate the process i/o. Converting the array to a string every frame gives less then 2fps in Unity. The solution to this is to get mMap files working in .net 3.5. I tried many different ways before settling on the additional process, with no luck. I do have a potential solution however, but could use some input from any .net guru's out there. Inverse Kinematics The IK code is all custom, but it's pretty amature. I rely on SOHCAHTOA and the law of cosines for everything. Unity gives me a lot of cheats that aren't available in real time. Vector3.distance for example easily gives me the distance between two points. It all works though, and I plan to expand it out to more joints. The neck arm also allows rotational target matching. PID Controller Servos Each servo has it's own tunable PID loop which uses the error between the actual and IK servo angles as its process controller. This output sets the speed of the servo on a frame-by-frame basis. I only have a basic knowledge of PID tuning, so if anyone out there would like to share some advice it would be greatly appreciated. Gait Sequencing & Steering Right now the only gait sequence that exists is walking at a set speed. Steering is the last thing I still need to do. I wrote some simple stride length adjustment code, which allows setting the desired stride length for both the right and left legs at the beginning of each stride. The actual steering is adjusted by a PID loop which decreases one side's stride length by a percentage of its default length. So my stride length is 2 meters, and the steering PID can shorten that by up to 5%. Terrain Mapping & Active BalanceThe hexapod now has full terrain mapping and navigation capabilities. Instead of using the vessel height to position the ground and foot targets, each foot target is now placed on the ground directly beneath it.Each hip target is now set according to the ground position of it't foot. There are two ways of setting the hip targets. Right now the hip targets are set at the average height of all the foot ground positions plus the target height. I've realized since recording the video it would be best to just set the hip targets so that the vessel is always the target height above the ground. Or some combination of the two. The first method helps going up hill, while the second is preferable for down hill. Also setting the hip height half way between the highest (foot ground + target height) and the lowest would be the way to insure each foot has the best chance of hitting it's target when going over extremely rugged terrain.The vessel also knows if it is traversing up a hill, is level, or traversing down a hill, and sets the color of the ground accordingly. Right now nothing changes according to that, but eventually the gait will respond to the different slopes. I tried taking it out to the mountains but I still need to find a way to orient the gyroscope to a level surface, even when the launch point is not level. The triangle begin drawn on the ground represents the leg group that is actually moving the hexapod forward. VR Implimentation As soon as I can get the camera feed from KSP to display to a render texture in Unity, I will be able to start moving forward with VR implementations. I have several things that will be pretty easy to accomplish right off the bat. I will be able to have the robotic head match the rotation of the HMD head, and display the camera feed to a HUD. I will also be able to control the arms of the mech using touch controllers. I have some thoughts on getting VR to work natively in KSP as well. This has been done before, with mixed results. I'd like to see if I could do better. Collaboration and Testing Let me know if you'd like to contribute in any way. If you'd like to help and know any Unity/C# that would be great, but I could use help with tuning and design as well. There are a lot of variables that need to be tweaked, as well as design changes to the mechs themselves. Let me know if you have any interest in helping and I can probably find something for you to do. There is also the potential for a real life counterpart. This is something I would definitely need help with, as my hardware skills are almost non-existant. I am planing on buying a frame in the near future, and would love to have some help implementing my Unity controller in the real world. If this interests you, there is lots of info already on this thread page.

I stopped working on my mods for some time, however I want to update them for 1.8. Thankfully the parts work just fine in terms of functionality, the problem is that the textures now look very strange. It looks as if half of one part has one shader while the other half has a different one. This doesn't happen with all parts, so I'm at a loss about what might be going on here. Any input would be greatly appreciated. Below are some images of the weird looking textures Strange dividing line: Another strange dividing line: Normal looking one, for comparison:

Buenas: Algo ha debido pasar con la última actualización de Kerbal con la expansión "Breaking Ground", porque resulta que cuando aterrizo en Muna o Minmus, si me acerco a alguna "anomalía" para tomar muestras, el juego se "crashea", y aparece un mensaje de Unity. Es más, si tras esto, vuelvo a entrar y cargo partida, y voy a algún Kerbal sobre la superficie, también crashea….. Es desesperante.... ¿Le pasa a alguien más también?????

I'm trying to follow DMagic's UI tutorial, and I am currently trying to get my head around interfaces - and buttons. I can call any public function with OnClick(), but I'm not sure how to send that event to the KSP assembly. What I've thought of are setting some variable to a certain value and checking every once in a while through the interface if that variable has changed, and calling a GameEvent which gets picked up by the other assembly (I'm not sure if that's possible). Would either of these methods work, or is there a better way to do this?

Hey guys. I've been having some trouble with Unity lately. (I'm using Beale's beginner modelling tutorial) Whenever I drag the model and collider OBJs with its textures into Unity, the materials folder does not appear. I don't know if there is a work around it (AKA Beale's way isn't the only way.) But if anyone has a clue as to why it's not working, that would be great.

So whilst trying to put together some new model for a current mod I opened the project in unity (5.4.1) which I had built the entire mod in originally only to find tat the 'Part Tools' in the inspector is broken. I have no function for the KSP Part Tools (script) no option to set 'game data directory', no option to 'write', Nothing! The little expand arrow expands nothing, there is no option. As you can imagine I find this concerning as presently I can creating no new models as a result. So far I have tried: Re-installing the latest PartTools (both onto my machine and into the project). Restarting my machine (numerous times!) un-installing and re-installing my current version of Unity (5.4.1) Installing the latest version of Unity (5.5.1) and importing the project there. The result is the same; my KSP part tools script in the inspector has no functions/options. I have google'd and scoured the site and I can't see any solutions, any clues?
