ZBRUSH... weird light effects after BPR .

ISmokeRodeo

Real time

BPR


There are some weird lines that act sort of as a specularity even though in the material modifiers is at 0. Please if you can help me get rid of those since I was going for a more realistic skin.
I get the same problem with other materials such as the default SkinShade and I never encountered the problem with other projects. Maybe the light is messed up but I can't tell for sure since I was not experimenting much with it...
PS: I know the model is lacking a lot of details.

There I used the Lights and Mat from http://www.zbrushcentral.com/showthread.php?24264-Skin-material-and-Light
... I don't get it... :S

This is something I tend to run into as well. It seems to have something to do with scale, such as if I have a human model it renders fine, then I put a large plane in the scene and I get these crappy shadow artifacts that don't go away no matter what BPR shadow settings I use. If anyone's found the solution to this I'd love to know.

Witch Zbrush vesion are you using?
I exported my model and then imported it so I can wield the torso, arms etc. and then it shrank a lot
I think that's when it started showing the weird thingies all around it...
I have no UV on in just a basic polypaint ....
I spent 20 h into anatomy on the model I'd really hate to throw it away.

Ah well, Nevermind. I have gotten that effect before with mats when my mesh flow was slightly distorted but yours looks fine.
