Is it possible to use ColorSets/painted vertex colors?

[Joss]

Is it possible to somehow use vertex colors/color sets as a, let's say, diffuse color?
I have some procedurally generated geo with some tricky color mapping/vertex colors, so there's no any other way to texture map that or such.

I don't think so,
vertex color is not supported in Octane core.

Right, this trick could also work in Maya, thanks Jo.
In the Houdini example, 1 channel only is transfered from point cloud to UV and then used with a gradient as a mask.

But as Joss want to transfer color we need at least 3 channels R G B, and UV only have 2 channel U and V,
so 1 UV set still can't transfer Color information, we need to use at least two 2 UV set.
Also I can't see an easy way to connect in maya colorpervetex to UV,
one way woud be to use nodes from SOUP plugin.
Else we can simply copy by script the pervetex values, Red and Green to UVset2, Blue and Alpha to UVset3.


@Joss
How do you generate proceduraly your ColorPerVertex, is it animated ?
can the same process directly write this values in 2 additinonnal UV sets ?
