Best file format for embedded color data into 3D surfaces

I need to be able to import a polygonal mesh that has embedded color information into Rhino. Is the best file format for this OBJ, FBX or something else?

And after I import it, how do I easily see/ toggle the color data in Rhino? Shade?

I’m working in Autodesk’s Alias so any particular expertise with this would be greatly appreciated!
Thank you!


in case your mesh as embedded vertex colors, there is no built in command to toggle them in rhino 5. You might use the script posted here for that.
