I'm on Driver 572.83. Latest C4D and Octane builds. RTX 4090

Edit1 : tried clean installing the driver. Didn't seem to fix it.
Edit2 : tried multiple different studio driver versions.
Edit3 : Issue is happening on 2025.1.3 and 2024.5.1 but on 26.110, it's rendering fine.
Edit4 : Removed all other plugins just in case, nothing changed
Edit5 : Deleted the prefs folder of C4D. Didn't seem to help.
Edit6 : Clean installing c4d didn't help.
Edit7 : Included a log from C4D 2025. Sphere with a red standard material that's rendering white.
Edit8 : This isn't device-specific. I tried my other machine with the same 2025 build and Octane build. It's running on a 2x4080. Same issue. man, this completely screwed me over as It went unnoticed while I was working and it messed up multiple days worth of rendering.
Edit9 : 2024.1.2-[R3] Build 0102 has the same issue.
Edit10: 2024.1.2-[R2] Build 0101 renders fine.

TLDR: Since 2024.1.2-[R3] Build 0102. Standard material don't render correctly. Same issue appear to be happening on the 2025 version.
This is most definitely related to the support for rendering RS Materials. Seems like it completely broke standard materials. bummer.
I'm reverting back to 2024.1.2-[R2] for now.
