Rename texture sets or re-link if renamed in Maya
I rely on texture set names as a string when I output my texture maps. This is important as a working pipeline to have everything named correctly and export easily. Right now if I want to change "Cat1blue" to "Catblue1" I will have to re-export a fbx with both material, copy and paste in painter (which sometimes mess layers up), export a fbx with just new material just to get rid of old material in Painter. And while it kinda work, I am still forever stuck with an error message in the Log that says I am missing the old material.
Let me rename/add/delete texture set in Painter. During reimport, ask me which texture set from .fbx is my renamed texture set in Painter.
