I just used vertex painting the first time. First it seemed to work and the colour could be seen after pressing alt+z. Then I painted a second time and now after leaving vertex paint and pressing alt+z the painted object is black. Pressing v the colours are right. I’m using publischer 2.25.
Hmm, maybe a restart helped. But I figured out, that in the realtime engine everything ist ok. Also I realized, that the real colour is only seen in realtime, or maybe in a rendering but not exactly, when just pressing alt+z. I hope this is right, if not, then just correct me.
