I want to edit a game model and I can't join the meshes with CtrlJ because the model will not work in the game anymore. If I use P in Edit Mode, the meshes will split into even more meshes than before, with different names, and it will not work anymore.
The model is separated into multiple meshes.
I can edit the vertices of each mesh, but I can't edit multiple meshes at once, so that they stay "synchronized".
Any idea how to do this without CtrlJ or a way to "unjoin" keeping the same meshes names before joining?
