Can I vertex paint a skeletal mesh?

I have an imported skeletal mesh that I’m trying to paint. When I select the paint tool, I click on the character but there is no circle over the skeletal mesh at all. When I continue to mouse over the weapon that he’s holding (different mesh in the blueprint) the circle appears and I’m able to paint. I couldn’t find anything in the documentation about not being able to paint a skeletal mesh so am I doing something wrong?

Did you find an answer for this?

I concluded that you can’t use this feature on a skeletal mesh. But that was a while ago, I haven’t tried since.
