Firstly, I imported a ply mesh to Blender 3.3.0 and colored it by attribute. I selected place in edit mode, where I wanted to draw the texture and created Smart UV Project. Then, I followed by many tutorials and blocked in one moment. I try to draw a texture in stencil mode but it doesn't work in Texture paint interaction mode, but it works on the paint mode.
It's my settings
