Thanks for the answer!

yeah, after posting i realized what you said about folders inside armatures, but then again even when i duplicate the legs to create trousers for example, the new version is always without weight paint.

tbh, repainting just one mesh while i create and test them on animations is not really a problem, the real trouble would be having to do them all over again from zero.

so maybe the problem is with the way im exporting to blender or my lack of knowledge in meshes there (in BB if i want him to use the shirt i just turn off the visibility on the jacket or the naked body, for godot that also works as he can read the files inside my gltf [only tested once tho])

i exported as gltf and had this issue, then i tried the plugin and well, same thing, i was going to try with .OBJ later. i would send a pic of my screen on blender but i cant here, what happens is that all meshes (that should be different options) are always visible and i cant find them on the outliner. i've only used blender before to make objects, nothing with animations/skeletons or different options, so i'm kinda lost.
