Strange artifacts in perspective mode.

Here is a screenshot of the polycube at subd level 1 after turning on perspective mode in edit mode. Also visible are the geometry and display settings.

I’ve circled the artifacts that I see. Does anybody else see the same thing? If not then I’ll post my system specs.

The artifacts persist in best render mode too.

Where is the option to turn on perspective?

It’s not in front of me at the moment, but I think it’s in the draw menu (it hasn’t moved).

The easiest way for me to find it was clicking Rapid UI, then the perspective options at the bottom left of the screen… if you click back to classic UI, it will keep perspective.

I’m still not sure where the perspective option is from the classic UI.

I did a bit of reading about those whacky matcap materials, and I thought a test was in order to see if it had to do with the baked in light or not. The artifacts appear with the fast shader and the basic shader too.

This seems to happen with non planar quads. I think that’s normal. ZBrush display isn’t optimized for low poly meshes.

Persp in classic mode is in the Draw menu (edit…as bill said correcly :lol:

That’s the polycube tool that ships with Z3. It could be non-planar, but I doubt it.

You’re right, in perspective mode it happens with non planar quads too. Do still think it’s normal though, have seen it on every zbrush installation I’ve seen so far. It probably comes from the speed optimization of zbrush’s drawing algrithm.

It doesn’t seem to be an issue in ZB2.

I did another test. It still appears when dsmooth is turned up.

Oh well. :slight_smile:
