Uvs have nothing to do with vertex color. I've used the vertex painting tool and my own imported meshes with vertex paint on them with no problems. What shaders are you using?
I cant for love of god get this to work! I use the Simple Vertex Blending in Our Schools unity. But i cant get the setup to work between two diffrenet textures. Any tutorials? I've tried to google but every time i do that. They just show what it looks like and not the setup!! gaaaargh! Thanks in Advance Wisam
found out a bit of the problem. If i would make a simple plain in unity, and use the vertex color. It acctually works. But using my island (which is Uv:ed) is forcing me to move my island to where the pensel works :S. The Pivot is centered, history and transform is fixed. hmmf.
