Since no one has tried Max6+MentalRay yet, here is the best I could do. Can’t really do anything about the banding like I can with Vray unfortunately (like lowering the blur setting in the material editor). Mental Ray in Max seems to ignore those settings, so I figure the default 1.0 blur is being applied and can’t be changed. Playing with the various dispalcement settings can mitigate it some what, but also tends to make for a lower quality displacement at the same time (looks less like banding and more like a bumpy orange skin). No big deal to me though, since I don’t really use MR for anything at the moment.
PS: Yeah, could be considered a failure I suppose. Figured I’d post it here anyways though so that no one got mad at Zbrush when trying to use it, hehe.
