Vertex paint question

Hi all, If in vertex paint, you paint a strong colour on the outside corner of a box and rotate it, the back face that connects to that vert remains uncoloured. Is this correct?

It would seem that as it’s the vert being painted, the backface should be affected too. Or can it do that and I’m missing some kind of setting? :slight_smile:

Actually, I’m not sure why this has been moved to this forum as it’s particular to 2.5.
