Do you need full color, photo-quality prints? What do you mean by rendering?
Yes full color photo realistic.
We take 3d engineering CAD models of our casegoods setups and "lay-on" the veneer grain/direction, custom finish color, hardware finishes, etc. Then as needed; add a high-rise city scapes in the window if there is a window in the simulated space, plants, knic-knacs, etc.
So our client get the real look of what they might purchase without actualy building them a physical mockup.
They might be ordering hundreds of this one setup or hundreds with slight variations.
