So here is another render. Turns out the errors seen on the Nova were caused by the smooth polygons setting. So I turned it off. Despite the errors in the previous render I still like it better than this one. Pete

Looks great. I noticed the left front tire is passing through the fender a tiny bit.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

Yep. I've got the tread bump set to "1" displacement. I'm going to see what it looks like with no displacement. I also did a crappy job with the nearby trees. I think I should have just used trees from one of the environment backdrops

A tread bump like that we usually want to offset so it makes grooves, cutting into the tire. Instead of expanding the treads, you want to shrink everything that is not-tread.

Hook the displacement map up to a Color_math node. Set Value_1 = white and connect to the map. Click on Value_2's color and sample the brightest spot on the tread map. Hook the Color_Math node to the displacement channel.

This will cause the bright spot to be neutral - no change - and everything darker will be a depression. Thus - the radius of the tire will not be altered.
