The "optifine compat" shader failed to load about objmc

[Godlander]

i will add it next update, currently rewriting some formatting stuff and then will probably merge the two to just be one version that supports optifine but also doesn't lose out on anything

[Godlander]

it seems you're running on 1.18.1, not the latest version.
you should be able to fix this by adding the fog.glsl from the main branch, located at assets/minecraft/shaders/include/fog.glsl

Thank's, it works with the fog.glsl file of the main branch, the file is missing in the shader of the "optifine-compat" branch so that's why it didn't work ^^'
