Vertex Paint doesn't work with specific Mesh

Thanks everybody for the help!

I created a simple vertex paint material (material01) and here is a example of how its functioning!

but when I apply material 02 to the same mesh than, I start to get this problem where my faces disappear and I can’t paint the vertex colors anymore.

Does anyone know what is happening?

here is a sample of my vertex color nodes

Thank you very much guys!

What happens if you do this? :

  • Copy vertext colors.
  • Remove them.
  • Add the new material.
  • Paste vertex colors.

I just tried and it didn’t work.

I copy the mesh vertex colors from what I’ve painted with material 01 that worked and remove the vertex color. Applied the material02 and paste the vertex, they all still displaying like those dots, and not as faces.

What is curious is that the same material 02 can be applied in another mesh with vertex paint and it works based on the vertex paint from that mesh. but it doesn’t happen with this specific mesh.

any other advice?

I can share the files anytime if that would help.

Thank!
