Description of the Bug
Hello, I love this mod which seems to work perfectly, except for one detail that I don't explain: I applied random textures to brick blocks, dirt blocks and polished blocks, but they have a problem in common, where the texture applied to the different faces of the block (cube_all vanilla) is randomly designated according to my selection, the texture of the face of the bottom of the block (bottom face) is not chosen randomly and is similar, while in the 3D model of the block, each texture uses the same random texture

Steps to Reproduce
Create a 3D block model using random textures with a parent model "minecraft:block/cube_all", apply any random texture to it, in the same way as indicated in the wiki, then check in game the underside of the block in question

Normally functioning surfaces:

Underside surfaces not functioning normally:

To get a seed for the random texture, I multiplied the block position by the index of the side the texture is on. The bottom side has index 0, hence it would always end up with a seed of 0 🙃
It should be fixed now in Fusion version 1.2.8.
Thank you for reporting the issue!
