FAQ

Q> Can it work with Optifine?
A> Optifine might make it unstable and cause crashes

Q> Will this library be ported to Fabric/Forge/Quilt?
A> I am not planning to port it to these loaders since there are similar libraries that already exist for said loaders

Q> Will this library be ported to NeoForge 1.21.1+?
A> As of now NeoForge versions 1.21.2-1.21.11 are unstable and most of the features don't work (including post processing shaders). But as soon as stable version appear I will try to port it there
