I have minecraft version 26.1.2 and fabric mod loader . Everything works perfectly. Its just that Any pbr resource pack doesnt work.

Using Spbr with bliss shader (image 1) : results in invisible blocks

Using Spbr with Photon shadder (image 2) : Results in fully black blocks

Shader settings are perfectly ok and i tried it even with no mods still didnt worked.

Any help would be appreciated !
