last i have played was 1.12 with stoneblock where the strip on the side had your psi colors but in this version it is white. since i have not played that long i am unsure wether this is indeed a bug or a feature. On the ivory CAD there is a small pink Slither that is untextured/has a missing texture.

also the backside texture of the cad programmer stops rendering from a few blocks away

What mods are you using with Psi?

Could be a compatibility issue with the Oculus mod, works fine for me with the mod standalone. I also noticed this issue in my modpack, fixed by removing Oculus completely.

Yeah, oculus should be in the Pack. I just added psi to atm8. Is there any workaround since i use shaders?

Disable Block Face Culling in the video settings. Or make a tiny resource pack that disables it for that block only.

Fixed in 9458736?
