Does Vray support vertex colour shaders? If not, you'r screwed, unless you can translate your vertex colour space into a texture, which is -at least in theory- possible for some topologies. I know VRML supports vertex colours, so that would be a good way of getting the mesh across intact.

 

I think Brazil for Rhino has this option as I requested it in the past.

You might want to look at Vicente Soler's solution to this problem.

now i have figured out how to render vertex color with mental ray in maya,

but not in vray for maya. i need more time...

 

PICT_01_Grasshopper definition

02_Export as fbx

03_Import fbx file in Maya

04_Choose mental ray as render engine

05_Create mentalrayVertexColor in Hypershade

06_Assign a new lambert material to the geometry

07_Connect mentalrayVertexColor to Lambert color

08_Connect MeshesColorperVertexSet to mental rays ColorVertex Node

09_Render

for example there is a vertex color vray mat map in 3ds max vray just for this...
