RSS Overhaul by PhineasFreak · Pull Request #320 · KSP-RO/RealSolarSystem

PhineasFreak · 2026-04-19T07:50:26Z

Major update for RSS to try and bring it up to current KSP/Kopernicus standards and fix some bugs:

Should mostly be a non save-breaking update.
Complete restructure of the directory tree (built upon Restructure Folders #306).
All mod compatibility patches now reside under the (existing) "Compatibility" directory.
All RSS-specific patches now reside under the "Config" directory.
All RSS-specific patches are now prefixed with "RSS_".
All Kopernicus body cache files are now managed by Kopernicus itself to avoid bugs when upgrading RSS versions.
Added some Soviet deep space tracking stations to CommNet (ported from Realism Overhaul).
Added fallback PQS materials wherever applicable (not really necessary but good to have).
Added missing normal and height maps to Dione, Enceladus, Iapetus, Mimas, Rhea, Tethys and Triton.
Added the dwarf planet Eris (2003 UB313).
Renamed the KSCSwitcher patch from "LaunchSites" to "KSCSwitcher".
Renamed the NIMBY patch from "RecoveryBeacons" to "NIMBY".
Removed all stock PQS mods from all bodies (simplifies removal of various useless PQS mods).
Removed the "cbNameLater" parameter from the Earth. EVE and Scatterer effects will now show in all their glory on the KSP main menu! 💯
Removed all custom body indices for better compatibility with other RSS planet packs.
Removed support for the "RemoteTech" mod (use https://github.com/DRVeyl/RealAntennas).
Removed support for the "PlanetShine" mod (use https://github.com/LGhassen/Deferred).
Removed support for the "SigmaBinary" mod (not working in the latest KSP versions).
Removed the stock launch sites introduced with KSP version 1.12 ("Glacier Lake", "Cove", "Mahi Mahi", "Crater").
Updated the CB configuration files to make use of the newer Kopernicus "OnDemand" system for dynamically managing ScaledSpace textures (this also allows the Earth and Moon textures to be unloaded when not used and save memory).
Updated the Pluto and Triton rotation periods to use hard-coded values (RSS correctly now enforces the use of gravitational parameters for all bodies).
Updated the Earth and Titan oceans to use custom settings for better visuals.
Updated the MSFN CommNet stations to match the later, Apollo Network, configuration.
Updated the Saturn rings to use the new Kopernicus ring shader and replaced the ring texture with a much higher resolution one.

Bug Fixes:

Fixed the Sun light parameters for compatibility with the newer Kopernicus versions (this also allows for custom brightness curves versus distance from the Sun).
Fixed the CommNet part patcher being unable handle parts with more that one "ModuleDataTransmitter" modules.
Fixed the Venus, Earth, Mars and Titan AFG parameters for smoother edges.
Fixed the overexposed specular reflections of all gas giants.
Fixed the "TextureReplacer" mod compatibility patch to edit the existing node instead of creating a new one.
Fixed the hard-coded description localization for Oberon and Umbriel.
Fixed the PQS/ScaledSpace transition altitudes of many bodies.
Fixed the oblate feature of all gas giants not working at all.
Fixed the grass color and texture tiling of the KSC buildings (this does not apply if KSCSwitcher is installed).
Fixed the incorrect, relative to Pluto, osculating elements of Charon.
Fixed the missing AFG nodes of Neptune, Triton and Pluto.
Fixed the orbital inclinations of Deimos and Phobos being relative to the ecliptic instead of the equator of the parent body (Mars).
Fixed the Io, Europa, Enceladus and Triton color maps using false colors.
Fixed the Enceladus biome map alignment issues and added an extra "Canyons" biome.
Removed a duplicate gravitational parameter in the Titan CB configuration file overriding the proper one.
Fixed some minor typos in the EN-US language pack.
Fixed the incorrect horizontal mirroring and prime meridian of many bodies.
Tweaked the brightness matching between PQS and SS transition for all bodies.
Tweaked the initial rotation of the Moon (no Principia).
Reverted all PQS material nodes to use stock KSP terrain detail textures instead of the RSS-supplied ones (workaround until they are fixed).
Removed the custom PQS terrain quality settings from all bodies (possibly overwriting the user-selected terrain presets).

Known Issues:

The KSC monolith anomaly cannot be removed (it is part of the space center mesh).
The Sun has the stock yellow appearance instead of being white.

Other Notes:

All bodies require updated textures, these are available here: https://github.com/PhineasFreak/RSS-Textures-Dev/releases. Choose your download accordingly to the already installed RSS texture pack (or not if you want to upgrade/downgrade the texture resolution). Remove the existing "RSS-Textures" folder and replace it with the above. Beware, the 16k pack comes in two compressed .zip files due to GitHub file size limitations (use an archive manager to unpack).
Any vessels inbound for the moons of Mars (Deimos, Phobos) and NOT in orbit around them will have incorrect trajectories due to the change of their relative inclinations. Make sure to either delay the arrival of or put in stable orbits said vessels before updating.
RealAntennas support requires a big overhaul of the RealAntennas package to move the RO and RP-1 patches over to their respective mods. It will not work as-is (see RealAntennas stockification RealAntennas#79 and RealAntennas stockification v2 RealAntennas#95)

 	// inconsistent orbital elements.

-	!Body,* {}
+	!Body,*{}


This bothered me when I saw it. Still does. It is critical that this patch runs before all other patches that add a Body node. Previously it relied on the lexicographical ordering: RealSolarSystem/RSSKopernicusSettings.cfg before RealSolarSystem/RSSKopernicus/. The "/" sorting after A-Z.

You don't have that pattern now. You have Config/RSS_Kopernicus.cfg compared with Config/Earth/. I didn't think MM patch ordering had a file-before-folder pattern, I thought it was strictly lexicographical.

My suggestion is move this patch to BEFORE[RealSolarSystem], making it clear and giving you a more obvious sorting of this setup patch versus the global ones.

That is a very valid point and it should be a BEFORE pass even without name shorting (stock KSP mods use AFTER[Kopernicus] for example).

As of 2239a63 a better MM pass is implementated. The new pass allows base RSS patches (celestial bodies), RSS general patches (CommNet etc) and RSS compatibility patches to coexist without conflicts.

PhineasFreak · 2026-04-20T05:15:02Z

If anyone around here is knownledgable about how textures are set up for use in KSP please do chime in. The terrain detail textures RSS includes have a very shiny-like, almost glossy appearance, which is...suboptimal.

Surely this change would make this PR save breaking?
(github messed up the comment, this is referring to the cbNameLater commit)

PhineasFreak · 2026-04-21T06:35:11Z

As weird as it sounds, no! 100% drop-in replacement. Well, the Titan body configuration had a duplicate GM factor with less precision that overrode the proper one so there might be a very slight difference in the orbit (8.978138376543E+12 vs 8.9778648E+12, 0.00305%).

Edit 1: I could make a save-breaking change by reordering the body indices.

Edit 2: OK, I will break saves, I corrected the height offset of Vesta and Ceres when transitioning between PQS/SS (any landed vessels will float above the surface).

Clayell · 2026-04-21T20:03:20Z

If it is save breaking, then AssemblyInfo.cs can/should probably be updated as well. It's still reading 18.5.0.0!
I'm also surprised to see that there's no KSPAssembly attribute, which allows for other mods to declare a KSPAssemblyDependency on RSS. Can this be added?

PhineasFreak · 2026-04-21T21:06:43Z

I guess so, I am not well-versed with the C# side of KSP and mods (and should be done in a separate commit).

PhineasFreak · 2026-04-25T13:01:25Z

Poll: since there will be some save-breaking changes, would this be a good opportunity to remove all "flightGlobalsIndex" definitions?

siimav · 2026-04-25T13:03:33Z

There's different levels of save breakage. Pretty much nobody's going to care about vessels landed on Ceres. However every probe around every body getting deleted is a serious issue.

PhineasFreak · 2026-04-25T18:25:27Z

For the above changes add the following textures: https://github.com/PhineasFreak/RSS-Textures-Dev/releases/tag/v0.1.0

Select your pack according to the already installed RSS textures. Replace when asked.

- Let them match between standard and fallback shaders.

- Deprecate the use of fixed light settings in favor of the much more flexible light curves.

Before it was relative to the ecliptic but the inclination of satellites should be referenced to the parent body.

Adds some variety to these bland bodies...

Add the names of the new Enceladus and Triton biomes.

Minimum loading distance and collision meshes have been fixed. Size distribution TBE.

BurstPQS now allows higher PQS resolution to be achieved and with better performance. Further increases TBT.

- Move all CB textures to their own folders (necessary if asset bundles are implemented in the future). - Fix PQS detail textures specular brightness and blending level distances. - Add the new Enceladus and Triton biomes. These changes require the use of the new RSS-Textures-Dev packages!

- Updated the Charon osculating elements and fixed its relative inclination to Pluto. - Updated the Pluto initial rotation to match the proper orientation.

All four moons now have Jupiter as a reference and not the ecliptic.

- Everything now is referenced to the equator of Saturn instead of the ecliptic. - Update/fix all orbital elements.

- Everything now is referenced to the equator of Uranus instead of the ecliptic. - Update/fix all orbital elements. - Add unique orbital line colors.

Generally very minor changes except for the LAN (why so different?)

- This was an automated action, beep boop...

- Specify the missing end time and coordinate systems used for the JPL HORIZONS interface. - Add the original RSS osculating elements how-to guide link.

- Reset all biome science value multipliers to 1 (looks like they never worked in the first place - Kopernicus/Kopernicus#914). - Convert more missed COLORKEY fields.

Patch instead of inserting the new settings to keep everything in the MM cache in one place (debug-related, no user-facing changes).

For testing purposes only!

They are not needed anymore.
