The sides of blocks when using LBG do not have any of the PBR textures (Normal and Specular maps). I have tried this with multiple texture packs and multiple shaders. I am using LBG with Sodium, Indium, and Iris.

i haven't used pbr with minecraft but presumably it's just like any other pbr implementation where there are bumpmaps alongside the regular texture. this means you would need to make those for the lambdabettergrass textures

This might work for override textures, but all auto-generated textures still won't work, I think I need to generate those textures too but I haven't had the time to properly look over this issue
