There are plenty requests for this already.
- something like blenders pose brush
- bone based rigging
Blenders pose brush is a intelligent masking algorithm under the hood. Doing mask gradients, searching for connected volumes and differs between close by objects due to topology flow (example: arm close to the hip, but connected to the shoulder)
Bone rigging would be a different class.
If so, a rigging specially for sculpting would be cool. I imagine posing without breaking symmetry, means you always can go back to initial pose, or, even better, sculpting is virtually added before posing, so you can use symmetry sculpting on posed object.
We’ll see.
Meanwhile you can select multiple objects and move their pivot point to pose all at once. But moved pivot point of a selection won’t be saved in your project. You need to redo it after reopening file.
