I have an armature and a mesh. Those 2 should move together like usual in rigging. The armuture's bones are all "deformable" and the mesh has its normals outside.
When I click the mesh, and then the armature > CTRL + P > Armature Deform With Automatic Weights it loads for a second, then I have the armature modifier and a bunch of vertex groups in the mesh data. When I try to pose the armature, the mesh doesn't move. Why is that? The vertex groups are all empty.
I don't know why that happens, it never was like this before. Also, i must have something to do with the mesh or armature because I just tried it with a default cube and 3 bone armature and it works no problem.
Please help
