can someone help me find a optimal mem setting?

ZBrush Usage Questions
#1

Hey everyone, I’m having serious issues with Zbrush 4.0.

Comp Sepcs:
Intel i7 920. 12GB of ram. 1TB Hard Drive. Nvidia GTX 285 2gb Video Card. Windows 7 x64 Home Premium.

Zbrush Mem Settings:
Compact Mem: 4096
Doc Undo:6
Tool Undo:6
Max Poly Per Mesh: 20
HD Preview Maxpoly: 6

Here are my issues. I get mem issues a lot. Masking/HidingPart of Mesh with CTRL+SHift and some times doing resym. I was successfully able to put out displacement map @ 2048 and normal map @ 4096. But for some reason after one successful run when I had to make changes and re-map I got mem error saying something about “mem-lock” and not having enough memory.

I’m getting tired of sculpting something and not being able to export anything after :mad:

Drop those undo settings back to the default value of 4.

Let’s say you’re working with a model that has 18 million polys – a little shy of your max. Each undo is basically a copy of your model. So even a value of 4 is going to mean 64 million polys being held in memory. A value of 6 raises that to almost 100 million.

Throw in a layer or two and you see how quickly that would tax a computer.

Lower undo values will result in better performance. ZBrush will always try to maintain more, sacrificing them only when it needs resources for other things. So even with a value of 2 you might often find that you have 4 or more available. But you’ll also know that when you only have 2 available it’s because you’re pushing the limits! Only raise the undo settings for short term bursts when you are about to do something that you’re really unsure about and then be sure to set it back down again before moving on to other memory intensive things like saving or creating displacement maps.

you know what really sucks… that answered all the questions i had about mem settings. i’ve tried so many searches with the term “mem” in it… and that never came up. :lol:

oh well. i hope this solves my issues with mem errors so often! i can get back to exporting DMs and NMs.

hey for some odd reason my max poly per mesh setting is stuck on 21.73. if i change it and save config and restart zbrush. it still stuck on 21.73. :frowning:

Yes, that setting goes to default every time you start ZBrush. The only thing you can do for now is drag the slider to a convenient part of the interface so it’s easy to set. You can also record a macro and have it run automatically when you start ZBrush.

even following what you both said… my computer is still having mem issues while spitting out normal maps :mad:

this is def frustrating…
