ZBrush crashes when exporting QuickTime (solution IS available page 3)

ZBrush Usage Questions
#1

ZBrush crashes evry single time I try to export a ZMovie in Quicktime format.

I read about this problem on forums and did not find a thread that covered it to the point where it is solved.
The other guys on the forums that had same problem were running different configuration machines. Some of them much more powerful than mine.

I’m running Zbrush 3.1 on a WindowsXP Pro, Celeron 2,9 GHz, 1Gig RAM machine. Motherboard is ASUS, Intel 865 chipset.

I tried everything. Turned off visual effects in the UI (read that it could help), tryied saving the ZMovie file first and then re-importing it into ZBrush for the Quicktime render, tried tweaking my machine’s settings, stopped most background processes, de-fragged my HDD just for any case…
Nothing worked.

Zbrush still crahes.

Help, please.

Hallo?

Hmmm seems like nobody wants to talk to you …

I just tried it out on both of my comps … it worked flawless every time.

Sorry it looks like it´s not a zbrush issue :frowning:

#4

It worked OK for me too but on seconds-short turntable movies.
I recently made a 1 minute long movie that was snapshotting the whole screen and not only the canvas and Oooops!..
ZBrush cashes every time I try to expport it.

what are your preference memory setting? from the test reported above is a specific pc problem not ZBrush.

Thanks.
Preference memory setting?
I don’t know. I’m new to Zbrush and I never messed with any program settings.
Guess they are the default ones?
Hmm, if my PC is causing this, then why this same problem has been reported by other people with completely different PC configurations?

#7

I got the same issue on my pc. Though I also get it when sometimes when I try and just render to preview my model.

Not sure but I think it’s a memory issue.

EDIT:
missed out the spec.

Windows XP pro
1gb ram
dual core processor

It used to work fine but since it crashed on my render it now happens every time. It renders the first row of the image and then BAM!

I rebooted and it still happens. :confused:

#9

How much free space is available on the drive where ZBrush is installed?

Have you defragmented the drive recently?

What is your Preferences>Mem>Compact Mem setting?

What about Undo and MaxPolysPerMesh?

Are you using one of the Glow materials?

#10

Ok this seems to be fine for some textures and materials and not others. If I use the normal matcap red and render it’s fine. If I use coloriseglow or glow then it will render for about half an image and then it crashes.

Also I should mention that I am using a saphire x1550 ati card

EDIT:

Sorry missed some of your questions there.
there is 110 GB of space my mem setting 256 when I last tried as it crashed before that and did not save the increase to 512.
Defraged last week funnily enough.
Undo 4
Polymesh 4

#11

oh and the ploycount on the model is 470,000 rounded up

#12

There is a known issue with the glow materials. Don’t use them.

#13

Ah! Shame, they look soooooooooooo pretty! :wink:
Well that’s my issue answered.

I hope Svet_P, that you get your own issue resolved soon. Infact I hope it’s simply the same issue i’m having. :smiley:

#14

Materials?
I am having a serious crash problem every time I try to render a ZBrush movie to Quicktime via the ‘Export’ command.
Could this ZBrush crash be caused by the materials that were captured in the ZBmovie? :eek:

#15

Edit - yeah, thats what I get for posting late at night, obviously I ment 20 GB. :smiley:

I am having a pretty bad crash every time I try to export a movie as well. The only way I have been able to fix it so far is to turn off one of my monitors. I use a dual monitor set up and if the secondary monitor is activated zbrush will crash instantly when I try to export a movie.

System Specs (old I know) Pentium 4 3.0Ghz Nvidia 5900 Ultra 256MB Abit IC7 MB 2GB Geil Ram 20GB free on C drive

recent defrag

I have the latest nvidia drivers, mb drivers and quick time version. I tried a clean install of zbrush. same crash.

I am using the default material.
I have tried playing the movie first and then exporting
I have tried saving and loading the movie in a brand new document.

#16

Only 20 MB free in C drive will be your issue, free up some space and see what happens.

#17

This same exact thing happens on my work computer as well, so I dont think its my old hardware.

work comp specs

Pentium D 2.99Ghz
3GB Corsair Ram
20GB free on C drive.
Nvidia 7900 GTX

latest quicklime, mb and video card drivers. clean install of zb3.1

Again, if I turn of one monitor it works fine, if I have both monitors running it crashes when I try to export.
This occurs on every model I have, no matter what the poly count or material.

I am attaching some pictures to help.

here are my steps:


  • Start zbrush
  • select any of the default models in the start up screen
  • hit “movie > turntable”
  • after it finishes, hit “movie > export”
  • you will see in the pictures, that if I have two monitors turned on the export window is missing the quality bar and the preview window.
  • two - five secconds later, zbrush will crash.
  • if i have one monitor turned on the export window looks correct with the qaulity bar and the preivew window shown correctly. zbrush will not crash, and will export fine.
I know the pictures below aren’t from a clean install but this problem actually gets worse if you have a clean zbrush install. zbrush crashes instantly when I hit export, no export window or anything; if I have a clean install and two montiors running.

Again, this has happend on two seperate machines.

#19

I too am having an issue with rendering and crashing, except Im doing a best render of the frame and not a movie.
My poly count is about 550,000 at a division level of 7. I found that lowering the division level helped but I want a high poly/rez render with depth cue. I can do a best render with the highest division level, but as soon as a I add in depth cue Zbrush crashes.

I have 4 gig of RAM and have left the compact mem settings to default…which is 256 I think? Should I adjust this setting for my render?

This is what the info said: “Compact Mem: This value represents the memory limit (in Megabytes) at which ZBrush will execute a Compacting Memory routine and begin writing to a special file on the hard disk instead of using RAM.”

  • A lower number = more hard drive usage; higher number = more RAM usage??:o
#20

Yup! Raise your mem setting to about 256 less than your installed ram in your Pc and then press CTL i to save.
