Right clicking illusion chest with a glass block (I have a Simple CT resource pack to support glass ctm)

Sorry for not responding the whole time, I had a tough time in my real life and had to pause mod dev...

Can you give me some more information about the mods/modpack/resourcepack you were using? I'm unable to recreate this crash. I'm having some issues with the texture though, but it would be a lot of work to get ctm to work and the problem with textures not connection is long known. But as I said, the mod didn't crash before and it does not if I try to recreate the problem... Sorry...
Regards, Manu

Hi, I have the same problem. When using CTM, if I try to change shaders, it crashes. With shaders on, the entire screen is white with blue spots. Crash report is the same. My mod list:
BlockCarpentry-1.16-0.4.0
Chisel-MC1.16.5-2.0.1-alpha.4
CTM-MC1.16.1-1.1.2.6
decoartive_blocks-1.16.4-1.7.2
OptiFine-OptiFine-1.16.5_HD_U_G8_pre2
worldedit-mod-7.2.5-dist

MC version 1.16.5

I think Optifine is a reason. I use forge + rubidium + oculus, no issues (despite I'm using JEM, enhanced textures etc.)
