Vertex painting won't work on mesh

Hi,

I’m following this tutorial on vertex painting on my mesh: Unreal Engine 4 Tutorial: Vertex Paint (english) - YouTube

I’ve done what the video says, set up the material and apply it to my mesh (screenshots below) however when I try and paint onto the mesh nothing happens. I’ve tried ticking the RGB boxes but still nothing works. The mesh itself has 104 verts. Any help? This mesh does originally have 3 materials so I’m not sure if it’s anything to do with that?

Did you try holding down the SHIFT key while painting? Your material setup looks good.

Hi, I just realised I was being completely stupid and forgot the whole point of “vertex” painting and didn’t actually try the corners where the vertices actually are hahaha! I’ve managed to successfully paint on it now, and yeah I was holding shift :slight_smile:

But because I have no verts in the middle, would I need to add verts in an external 3D program to the mesh if I want to paint in the middle of it?

Yes, that is correct. You would need to export the model to a 3D modeling program like Blender and subdivide the mesh to add more vertices to get the vertex count up to a resolution that provides you with adequate visual results when vertex painting.
