I am able to paint model with Vertex Paint. Colours are very similar to Normals. It is possible to have 2 or 3 normals per vertex. (smooth/flat)
Is it possible to assign multiple colours per vertex to use different colours with different faces?
Some how. I do not know how I was able to color model like that
I do not know how that happened. When ever I try to change colour then affects all three faces like that
