I applied 3 shaders 1 for each vertex group I made. I created the shaders in object mode first. I went into edit mode and selected a vertex group in face mode. I went to the materials tab and selected the material I wanted to apply. I pressed assign. It worked. I saved and exited that file. Went to the next asset. Created my materials as above. NADA.
It worked for one geo in one file and didn't work for another geo in another file. How is that possible? Am I doing anything wrong?
