I'm trying to create a modpack but the mod doesn't seem to work with shaders. Is it incompatible? When I turn shaders off, it works as intended but as soon as I turn it on and break a controller block, the game crashes. I updated OptiFine and downloaded the latest dependencies for 1.18.1.

Version Info

• Minecraft, 1.18.1
• Moving Elevators, 1.3.5

Are you using OptiFine?: Yes

Steps to Reproduce
-Load OptiFine shaders
-Place down controller block
-Break controller block

OptiFine changes a whole lot of things, yet OptiFine does not say what it changes and it is closed source. It also changes a bunch of things from the way Forge normally handles them. For example, the crash you encountered is something that can never happen with just Forge.
This makes it pretty much impossible to know if something will break with OptiFine installed and I am not going to spend my time specifically testing random things with OptiFine installed.
For Moving Elevators, this means it may simply break when OptiFine is installed.

I fixed this particular crash now in Moving Elevators 1.3.6.
