How to render a wireframed picture in Vray-rhino?

I’ve once seen some pictures rendered with vray-3dsmax, it’s cool with all the isocurve visible! It really useful for a presentation of product, and has good style.
With default rhino renderer we can render the isocurves but in Vray-rhino I have no idea of how to do it, can you tell me?

At the moment the ability to render isocurves is not available within VfR

Have you tried technical shader?

I’ve gotten some pretty good results. Check it out here

the default Rhino render engine (Rhino Renderer) will render the isocurves. Just set the rhino renderer background to be transparent. Turn on Render Isocurves and Text in its options. Render and save as a png. You can take that into photoshop and then composite.

Here’s one i did with 3 renders. 1 vray with normal materials like gold and stuff, then 1 with all plastics to represent my rhino layer colors, and then 1 from rhino renderer using wireframes.
