Previously I asked a question about how to make modular characters, but now I want to know the correct pipeline of rigging 3D modular characters . Is necesary weld every vertex or I could combine the meshes to make the rigging?
Nothing too special except you need to make sure stuff that should move together has the same vertex weights. Btw.. I guess you mean skinning instead of rigging but if you want to build a rig then I don't know of anything that would work differently for modular characters.
