Is there a way to sculpt an object onto your rigged/shaped keyed model without redoing the entire rig? for example: I want to sculpt a unicorn horn on the head of the pony model but it is rigged and it has shape keys.
Hum, best is to add that as a separated object.
It’s possible to edit the mesh making sure you are on the “Basis” shape key.
It can work for small stuff but it’s easy to break the model, you’ll probably have to rework the shape keys and so on…
However, you need to be cautious when doing so, if you go wild and edit the mesh like you would without the rig, doing multires, dyntopo or else it’s going to break very quickly IMO…
