Copy vertex colors between meshes

[Metin_Seven]

Hi @kkar,

@kkar

First of all, are we talking realtime or rendertime?

I use a black and white vertex color channel as the Factor in a MixRGB node, to mix two colors at rendertime, using Eevee or Cycles. Multiple vertex color channels allow for more intricate color area mixing.

I did not try GOZ with multiple vert colors, but I tend to remember that it carried vert colors both ways.

I haven’t got GoZ for Blender installed anymore, but it’s been tried and layers currently get flattened to one vertex color channel.

Another option can be to use R,G,B as individual masks areas in ZBrush. You can use Vertex Col Master to use each channel. That way one polypaint can hold 3 different masks if you will.

Interesting. The only drawback of that would be that a color can’t overlap an other color. Using blend modes in a MixRGB node, you can create interesting blends where black and white vertex color channels overlap.

But maybe I don’t understand it correctly, and there’s a possibility to draw with the R, G and B channel separately in ZBrush?

Thanks for thinking along, appreciated.
