What happened?

When I loaded Complementary Shaders reimagined when playing Minecraft, the game crashed.

Steps to reproduce:

1. Open Minecraft with Complementary Shaders, Sodium, and Iris (all latest versions as of this post)
2. Start a new world
3. Activate Complementary Shaders Reimagined

Attached is the crash log file. When I ran it through an AI bot (Google Gemini), it mentions the main cause of the error is an undefined or nonexistent object, as mentioned close to the top of the log.

Minecraft Version

Minecraft 1.21.5

Iris Version

iris-mc1.21.5-1.8.10

Operating System

Windows 11 Pro

What is your GPU?

Nvidia GeForce RTX 3070 (EVGA FTW3)

Additional context

My actual playername has been replaced with "PlayerName" for privacy. Please keep this in mind when reading the startup log.

Also, it appears that Minecraft did save properly before the crash in the log file.

Also, the issue seems to not to happen with a specific shader. The game crashed when I attempted to load BSL shaders as well.

same problem

This issue seems to be related to the Color Space setting. For me, any color space other than sRGB seems to cause this crash. When using sRGB I do not get the crash. Presumably there is some sort of bug with net.irisshaders.iris.pathways.colorspace.ColorSpaceFragmentConverter.

That works! thanks!

Fixed, will be released with Iris 1.8.11.
