hello friends, I'm trying to rig joints onto a custom character model to use as zombies. I took joints from a zombie asset, and replaced the zombie model with my model in maya. Then, i positioned the joints correctly onto the model before binding them together. When I try to export this using the cod plugin, it gives me an error and a couple of these in the script editor:

WARNING: Unexported joint 'tag_stowed_back' is influencing vertex 'mei_edit:Mesh_0715Shape.vtx[32]' by 99.985361%
WARNING: Unexported joint 'tag_weapon_chest' is influencing vertex 'mei_edit:Mesh_0715Shape.vtx[32]' by 0.003844%
WARNING: Unexported joint 'j_spine4'      is influencing vertex 'mei_edit:Mesh_0715Shape.vtx[33]' by 0.406341%

WARNING: Unexported joint 'j_shouldertwist_le' is influencing vertex 'mei_edit:Mesh_0715Shape.vtx[33]' by 0.262726%

there's a lot more.

I think you forgot to select some of the joints while exporting. Make sure you select all of them before you export a rigged model.

i click on the tag_origin of the joints, which highlights them all.

Clicking on tag_origin does not select them all, you must select hierarchy from Select/Edit menu (depending on your Maya ver).
