Any solution why the 3d textures are not visible and others look dark for no reason? I am using Seus e12 in minecraft 1.16.5

I have no idea what could be causing that🤔
Maybe options like "alternate textures" or "natural textures" ?
Or maybe an incompatible mod ?

PTGI E12 doesnt have parallax effect. Parallax of PTGI starts at HRR Test 2

But I think the problem that @R-A-I-D-E-N is pointing out is the lack of proper shading on some blocks. I have no idea of what could be causing that, try the same place with another shader to check if it’s a shader problem.
