I have a skull already modelled and im wanting to use metaballs to create the cheeks to form the desired expression (Yes I know bones cannot form expressions).
How would I go about this? Or is there a better way to achieve this?
You can’t fuse metaballs to meshes directly. They don’t function the say way a mesh does. The surfaces for metaballs are generated dynamically. You would have to convert the metaball into a mesh, then boolean it into the skull, and that wouldn’t be any different from just doing the same with a regular sphere.
It makes more sense to sculpt these changes into the skull.
