Problems with Polygroups

[twilightexplode]

First things first, this is my first post, although I stalk through here fairly often to look at sculpts and get inspiration.

With that said, I am having some serious issues inside of zBrush right now, and I tried to look it up on the forums and help document to no avail.

I am working with some geometry I imported from Maya 2014 into Zbrush 4r6. I bumped it up to about 2.3 million active points and then auto-separated it into poly-groups. When I isolate one of the groups, work on it, and then make everything visible again, the geometry goes back to looking how it did before. If I isolate the geometry again, the work I did shows up on the piece.

Has anyone else encountered this? I’m getting a little bit frustrated and I’m trying to avoid the hassle of a reinstall.

The purple ‘brick’ from the first screenshot is also the orange ‘brick’ at the top left of the second screen. The second screen is what it looks like before and after isolation.

I tried messing with the QTransThreshold as suggested by someone I know, I was also looking for a factory reset button but could not find one, and I tried restarting and then using 4r5 when that didn’t work, but I had no luck with anything.

I am running Mac OSX 10.7.5.

EDIT: Sorry, I would have linked the screens in the first post, but I was in a rush.

are you isolating polygroups or switching tools? Your polygroups shouldn’t be changing color during isolation.

Are you running ZB4 R6 P2? Your screen grab doesn’t help too much. How many subtools etc? Isolate how?

I tried to run the updater and it said there were no updates found, so as far as I know it’s as updated as possible. I have no extra sub-tools, and I’m isolating using control+shift+click. Is there another way to isolate?

Are you sure your bricks are single thickness? It looks to me as though you have sculpted some inner polygons which simply don’t show when all the bricks are visible. That would also explain the different polygroup colors.

When you say single thickness, what do you mean? Are you referring to the polygons having faces inside when I made them originally? As far as I know, they are clean geo, but my version of Maya is always giving me issues for no apparent reason, so I can’t be completely certain. Here’s a screen shot of the original geo in wireframe, though.

How, exactly, did you get the object into ZBrush?

[twilightexplode]

Imported from Maya 2014 as an .OBJ, and then imported it into zBrush.

Yes, that’s what I meant - two shapes, one inside the other. As has been mentioned, the polygroup colors don’t change when you hide/show polygroups, so your purple polygroup should always be visible. The orange brick appears to be different geometry but at this point we’d have to examine the model to see what’s going wrong.
