Memory Error

ZBrush Usage Questions
#1

Ok please bear with me as I am not the hugest techie. Feel free to laugh at my descriptions.

I’m having major memory issues in ZBrush. I’m running the programme on a dual processor PC, 2 GIGs of RAM. I have set my Compact Memory to 1655, Tool Undo to 1, am working at half the document size i usually do. Even when I have just opened a file & am merely hiding parts of my mesh, Zbrush gives me the ‘Insufficient Memory’ error message. Right now I tried to subdivide a section of the mesh (it was about 495 000 polygons), & the ‘Insufficient Relocated Memory’ message kept popping up until i actually had to close ZBrush. i set my MaxPolyPerMesh to 6.00. All other applications run very smoothly on this PC.

Besides that all actions are very slow. Even rotating alphas becomes painful.

Is this a ZBrush issue or am i missing something obvious here?

If u need more info just shout.

Please help. I am loving working in ZBrush - this is just becoming a serious pain in the butt.

Thanks :wink:

Two things to check:

  1. Make sure that you have a lot of free space on the drive where ZBrush is installed. ZBrush uses its own virtual memory file, and you’ll get this sort of problem is there’s not enough room for it.

  2. Defragment your hard drive. Having 8 GB of free disk space is no good if that space is so fragmented that ZBrush can’t make efficient use of any of it.

Thanks aurick. Although I checked both, & they’re fine. Here’s the wierd thing - i just tried to subdivide the dragon’s tail (80 000 polygons or so), & got the error msg attached.
So ZBrush crashed, & THEN i tried opening again & merely loading the tool brought up the ‘Insufficient Memory’ & then ‘Insufficient Core memory’ messages repeatedly.

:confused:

Out of curiosity, what are your other settings in the Preferences palette? Specifically, those for Performance?

Is your computer dual processors, or is it a dual core processor?

OK, my settings for performance are:

Multidraw: on
Multirender: on
QuickAndDirtyEdit: on
QTransThreshold1: 0.25
QTransThreshold2: 1
QEditThreshold: 4
H Priority & N Priority: off
I’ve set my MaxPolyPerMesh down to 5.00

I’m working on a dual core processor. The machine’s pretty new & speedy

Somehow I think that this might be slightly related to me being a newbie & not understanding general workflow correctly. I hid sub sections of the mesh & subdivided them, instead of isolating them as separate tools. I therefore lost all my subdivision history. I’ve subsequently done a lot of reading up on the topic, & am going to start again from scratch.

Hopefully I wont experience the same hassles…if I do I’ll let u know!

Thanks a mil for the help. This forum is fantastic. :smiley:
:cool:

One other thing that I’m aware of is that Dual Core processors came out after ZBrush 2. The MultiDraw feature works fine, but MultiRender has been known to create problems on some machines running Dual Core.

Thanks for the reply aurick.
I’ll turn it off & see if that makes a difference.

Thanks again
