my problem has to do with a vrm model that i imported into Blender. I attached the mesh of the boot to the amature with automatic weights. For some reason if i test it, when i move one leg the mesh of the other one comes with it.
One possible issue is that the meshes may possibly be linked to each other, so when you move/alter the mesh of one, the mesh of the other is moved an altered as well. You can try separating the meshes/objects.
- Select the boot
- Go to Object-->relations-->make single user-->Object & data
The other issue is that you may have somehow linked both boots to the same bone/armature.. You may have to unattach them and reattach them separately after making sure that only the materials/texture is linked, and not the meshes.
