I know that Optifine wasn't really meant to be in this mod pack and it shouldn't matter to the pack creators about other mod compatibility but I was hoping that this could get fixed. Basically, whenever either of these two settings have a value >0 some textures turn into basic colors. I have only seen this on the wooden glass and basically all of the CBMicroblock glass, but that's just because I cant try every block in the pack. Again, I know that it isn't really the creator's problem but others may have this problem especially since many people use Optifine for either performance or shaders. Below are a hollow glass cover, black stained glass slab, spruce window, warped window, and crimson window in order.

This is an optifine issue and happens on other modpacks too. Optifine anisotropic filtering and CBMicroblocks have the same issue on FTB OceanBlock for example.
