Hi,
I've been having a wierd problem when rendering outdoor scenes. For example, I have an asphalt parking lot with a curb and grass island in the parking lot. All were created using the "In Place" create tool, either extruded or sweep. Everything looks fine at this point, you can see the height variation between the top of curb and the lower asphalt parking a lot, roghly 5 inches or so. BUT, when I render it, it seems to make these different plans appear to be on the SAME plane. You don't see the varied height difference between the parking lot and curb heights. It almost seems as if there parking lot was filled with snow or something to the exact height of the curb.
Any ideas?
