algorithmic modeling for Rhino
Why don't you tell us which program you need to target, and we can try to find a solution.
Which formats do they support? Usually I open the vrml in Mesh Lab and export a texture based on the vertex colors. This is what has been the most versatile way to get vertex colors into apps that might or might not support them.
Did you look at that ?
it seems to work on Iray and Keyshot. I am also pretty sure I used it for Rhino 5/Vray
I did it in 1 minute.
Upload Vicente script
Change the name of "texture file" in panel
Make a Vray material
go in diffuse, click to add a texture, click on the checker, choose bitmap. Reuse the png that the script of Vicente output and that is done. You can render
