Name of Exported Textures
Control over how the exported textures are named.
In many case, we use the same mesh multiple time to bake decals or tillable textures. Which means the exported textures are always named the same based on the mesh name.
In this case, the texture should be named from the painter solution, not the mesh or the material slot.
yesss! in photoshop when you use the batch tool it lets you add a prefix, that is really all that is needed here.
