Mesh Painting Brush is too Big

I’m trying to use vertex painting but the brush is way too big. The size is even set to the lowest possible 0.000001.

I have the same problem.

Im in the latest UE 5.4, having this same problem in some of my scenes. Whats the fix?

Hi, If you go to the Advanced Tab in Mesh Paint Mode, check “Specify Radius” and then use the “Radius” Slider to adjust the brush size further.
