It actually performs remarkably well with mask maps as Control Nets. You can use a simple black background and white UV shells, that will give you OK results. But then you expand and use curvature maps just like you would with line art control nets, and then you have a controlled painting.

Even simple black/white shells work well, like here: https://x.com/_hackmans_/status/1644811607799738371
