I use Keyshot Pro for rendering using the OBJ export from MoI. The two programs play very well together.
Keyshot can also import NURBs. They claim it gives smoother edges, but I can't perceive any improvement, so I stay with OBJ. Sometimes I adjust the MoI exporter to suit the particular model if needed. I've never had an issue with tessellation.
I have no experience with texturing programs. Normal Maps in Keyshot is all I use for texture.
Thank you! I do have a car model that I started designing over a year ago. I need to put on the final details and make the tutorial. This one uses Max's SubD script for the body, and NURBS for everything else.
I'm a big fan of custom car builder Rick Dore - do a Google Image search on his name. He's heavily influenced by Delahaye and other Big Fender cars from that era.
The more times I read this, the more I learn. This is an tremendous resource for anyone interested in modeling cars, especially classic/vintage American cars.
I simply can not thank you enough.
Do you have a youtube channel or an Instagram account where you showcase more of your 3D models?
