So I have a model in unity that has 3 materials, for some reason one of the materials like...doesn't react to anything? I try adding an albedo texture to it as a simple shader and it doesn't display it, tried with poiyomi and same thing it only shows a flat color not the texture.

I tried in blender flipping the normals but that didn't fix it? I'm really stumped why this is happening. The other materials on the model are working correctly
