Memory Error when using groups loops...

ZBrush Usage Questions
#1

Hi there, ok so I’m working on a model thats 11.5mil polys - it’s a shark kinda thing, I polypainted the teeth a different colour so i could make the model as 2 polygroups (body and teeth) so would be easier for the texturing. Once I’d done that I go to click on the groups loops button and it crashes with a memory error saying it cant continue etc, I’ve got 8gb ram so this cant be the issue :confused: In the mem settings I’ve got compact mem set to max 4096 and in the bar at the top it says around 3700 free.

The only way I can get it to work is if i change loops to 0 but then polish smooths everything out and destroys all the surface detail, if I turn polish to 0 theres no different at all, trying loops at 1 just makes it crash again. Really dont know what to do now, could this be a bug?

Also is there a way to set the max compact mem higher than 4096, still got plenty more memory for zbrush to use!

Specs:

Windows 7 64bit
Intel Q6600 @ 3.2ghz
8GB ram
GTX260
ZBrush 3.5r3

Thanks, Mark

What is your MaxPolysPerMesh value set to? One thing I’m thinking is that if your model has a lot of polygroups then using GroupsLoops could be increasing the polygon count above what the MaxPolysPerMesh value allows.

If that’s not the case, then we’ll need step-by-step instructions to try and duplicate this.

Thanks for the reply :slight_smile: I’ve tried the maxpolycount at max 50mil and makes no difference. When do you click the Compact Now button? is that when you make a change to the memory settings?

The extra polygons it would be creating would probably be under a few hundred thousand as I made the teeth from masking and moving upwards so theres not a lot of resolution there.

As for a step-by-step…

  1. group visible (to make one polygroup)

  2. group from polypaint (I painted the teeth red the body white)

  3. del lower subd history

  4. group loops, loops = 1, polish = 0, triangle = enabled

  5. crash!

and if I click groups from polypaint more than a few times it’ll crash aswell
