Hi, I'm attempting to paint vertex colors in C4D for use in UE's nvcloth system. My path is C4D > FBX > CC3 > UE.
The trouble is I think CC3 is not importing or exporting my vertex colors. I can trace that the FBX exported from C4D has the vertex colors, as opening it in UE displays them. But any sort of trip through CC3 seems to remove them. I verified this by roundtripping C4D > CC3 > C4D. No vertex colors. 
I'm assuming this is a fringe request, but just wanted to see if anyone had a solution?

vertex color works only great on high resolution mesh, 
more vertex better and crisp results .
But that mean increase mesh density , that is not the goal of handy animtion objects and certainly not for game assets.
Therefore you need bake your vertex color into a uv based texture .

Thanks vidi, I should have been more clear. The point of my vertex colors is to control dynamics on nvcloth in UE. UE allows you to create painted weights via vertex colors - this makes painting dynamics maps much easier as you can do it in your DCC app (instead of painting them in UE, which only has basic tools)

I know very little about this but I know that iClone (and I guess CC as well) do support a vertex map, which is then used instead of a bump or normal map.

So it would go in the slot that is marked Bump map. There is no separate slot for vertex maps. So if it doesn't transfer, you could place it in the Bump slot (unless you need a normal map as well).

CCC do not support vertexpaint, only uv based maps. The map for clothsimulation is a greyscale map uv based too . 
It must be seperated import in the physic tab.

Yeah, thanks guys - but as I said this is specifically for Unreal Engine.  It doesn't matter if CC3 can't read or use the vertex colors as I'm not trying to do a cloth sim in CC3. The problem is that CC3 seems to be destroying the vertex colors. So when I attempt to pass a character through CC3 to UE, the vertex colors are gone.
