Alright, so I had some annoying bugs to sort out, but that should all be fixed now:
I just added the options for saving textures and also included an auto save option.
The “Clear Textures” option removes all textures that are not used by a material from the blendfile and also removes unused textures from the cache folder, where the textures that are created or edited with the addon get saved.
“Save Textures” saves all textures which are used by materials.
While I’m at it I’m just going to explain all the addon pref options:
Reverse Layer order reverses the order in which the layers are displayed in the layer stack
-Use any workspace allows you to use the addon in whatever workspace you want to, otherwise it will only work in the one called “BATS”
-Auto save saves a texture when you finish editing it with the addon in texture paint mode
The only thing left to add is the baking options for the masks and the exporting of materials. I’m hoping to get that done this weekend, which is also when I’ll be asking people for testing!
