visible Quads on Screen (not Polys)

ZBrush Usage Questions
#1

Hello,

i have a problem i have never seen before in zbrush… and i really dont understand it.
inside ZBrush (only inside the canvas) there are visible equalsided quads visible, very slight darker and lighter.
it is only inside ZBrush (i use other 3D-Software) and the quads move with the zbrush window (so its not an Hardware or monitor problem).
i attached images. i hope, you see it.
it is very slightly visible.
When rotating and moving the mesh, it is really annoying…

hope you can help me…

All you’re seeing are pixels. ZBrush is a software renderer and, in order to keep things responsive, avoids unnecessary anti-aliasing. In the days before BPR, it was recommended that the document was twice the size you wanted your final image to be and then the “A A Half” button pressed before exporting the image. BPR has done away with that, for models in Edit mode at least.

Different materials can vary the effect but you won’t get rid of it (and it’s always been there).

Marcus, I see what he’s talking about and it doesn’t look like pixels, it looks like polygons but without perspective…
Where he drew on the image describes large squares that I can clearly see as well, he drew right on them in fact.
I have seen this a few times as well, but it was a while ago and I dont remember what caused, or for that matter, fixed it.
Grabbing the first image and enhancing it will show you two things, one is its jpeg’d to hell, but the other is what he is talking about, its like a grid over his image. If you look even closer you will see that the squares he is talking about are in turn full of more squares.
Boosting contrast might help, but I used an HDR filter and POOF there it was.

I would upload my results but my internet connection is total crap.

Anyhow its definitely NOT pixels

thanks! yeah, that are not pixels. this is really annoying and at my home workstation (with much lesser specs than the one in my office) this problem does not appear.
i made two other screenshots that show the problem and show that this “grid” is fixed and not relative to object location.

i hope someone can help me soon. it is really a problem for a smooth workflow.

please look really close to the mouth-area and you will see the grid.
