I have found it to be a little bit of a pain on some models what each material is when setting them up inside of Transmutr. I really like the latest feature that looks into the material name - this is very nice! But some models, this will not work. For example, CGAxis names their materials “cgaxis_models_66_05_03”.
It would be nice to get a little visual swatch based on the diffuse map so I can tell what each material is.
Edit - I also just realized I can use the eyedropper, which is helpful. It might still be nice to see a swatch though.
