Describe the Issue
Some Prismarine variants missing in prismarine blocks, all slab, stair, and wall textures are missing completely

To Reproduce
place blocks in game
Using base 2.3.1, optifine and sound filters mod
Expected Behavior
textures to be present

Screenshots

My apologies I guess the PBR was the issue, it doesn't work in vanilla or with optifine.

Does this happen with just the base Unity? 2.3.1 for 1.16 has the prismarine fixes. Looks fine on my end.

Did you read the important notices? 😛

All textures are a work in progress and do not fully support the base Unity resource pack block variants.

I did, sorry I didn't clarify but even with alternate blocks off the stairs, slabs, and walls don't have textures
