Today I was testing the compatibly of the create mod with other mods. And while checking it with shaders, this happened.

It happens with the shafts but especialy with the belts.

I am running the create mod(v0.2.4d) along with optifine(G1_pre30) and forge(31.2.0) in Minecraft 1.15.2

Edit: I found out that a solution mentioned in another post works temporarily for me. It says you have to start the world with active shaders.

This issue has been marked as stale because it has been inactive for 3 weeks. It will be closed if it remains inactive for another 3 weeks.

This issue has been closed since it has been inactive for 3 weeks since it was marked as stale.

I think it is this buggy version the optifine, try this one OptiFine_1.15.2_HD_U_G1_pre23.

Well yes. We released Create 0.2.4e today to fix a few issues, including optifine. Test that, it should work.
