advanced rendering for AutoCAD
This never worked very well-- it's not scale invariant. We've had trouble with both engines-- I would avoid it until I get a chance to rework it. No clue which direction looks recessed.
this problem was mentioned before. see this link. It really should be fixed because de procedural tile can be a great tool. By the way, the bump value must be positive to make the joints recessed.
Yep. I haven't gotten to it because it's not a trivial fix.
Provided the join is dark.
