Getting normals out of ZBrush

zombie420 · Jul 2014

I've just created a tiling texture on the canvas and am trying to get a good normal map. I just used the simple brush and drug the normal material over everything but I can't seem to get a good map that isn't aliased to hell. Even with render/ best it's still pretty gnarly. Is there a setting I'm overlooking?

Can you post an image showing the issue?

In older versions of ZB I would get a problem where white spots would appear on a BPR using the NormalRGBMat. If that's what's going on then (IIRC) going to Preferences > Performance and turning off MultiDraw should fix it.

^ Try that and also

If you haven't looked into it, you can resize the document size. It's usually at like 1200x800 pixels or somewhere around there (depending on monitor size). You could set it higher if you're doing a grab-doc.

ALSO, I do believe the normal map material the zbrush comes with stock, is no good. There is a re-done version of it out there somewhere of a proper Normal map material.

The normal map material tristamus is talking about is here under the effects tab, 3rd row - http://pixologic.com/zbrush/downloadcenter/library/

Did you also turn on shadows when doing a BPR?
