Mac Zbrush 3.12 crashing while rendering

I installed ZB 3.12B but it’s still crashing at the end of the render, I’m afraid. I’m going to try rendering something else to see if its something up with my model. In the meantime, any suggestions would be much appreciated, Aurick or anyone else. Perhaps I should do a fresh install of 3.12 and then install 3.12B again on top of that?

Just an update for those who may have the same problem: best renders at 4000 x 4000 are coming out fine now - no crashes at all. I have no idea what if anything I am doing differently - maybe 3.12B just needed some time to feel at home :). Thanks Aurick for your answer and Pixologic for the upgrade.

I’m running on an iMac on 10.5.8 and on version 3.2. I used the turn table plus and it crashed 50 frames in. Prior to that, any addition of anti-aliasing in the render options or adjustment to the shadow curve or length results in a crash on the last pass. Anyone else still dealing with this?

You might try rendering with Preferences > Performance > MultiRender turned off. It will take longer to render but the multithreaded rendering caused a couple of crashes and unwanted artifacts in 3.0/3.1/3.5 on the PC. In ZBrush 3.5 on the PC the MultiRender switch is merged with the MultiDraw switch, try that if you cannot find MultiRender.

This solution worked for me. Thanks.

Here I still have those renderproblems. Soon (I hope) we have 3.5 (mac)
Did Pixo solved the problem or did they only used their energy for other ‘wows-tools’ and other cosmetica?
Imageplane, ZAppLink, Blur- and other 2.5d brushes, Rendering etc. all @$#

I am having the same problems everytime I create a large canvas anything over 3000 I will get a crash at the end of the render without fail, I dont have alot of matcaps in the startup folder, I have a macpro with 2 x 3.2 quad processors and 10 gig ram, MacOSX10.6, Zbrush3.2, I have tried dropping out of edit mode, Funnily enough I have done a render about 5 minutes ago at full canvas with simple redclay material on a default sphere and it has not crashed, but if I try it with a model with subtools and 1 or 2 materials it will crash.
Is this purely a mac problem, do PC users have the same problem.

@Matb
This is the way to solve the problem of this bug:
Light > Shadow > Uni (Unified Shadows)
Standard it’s set at zero, just set it more high. 20 or more works well.

thanks bas mazur,
I dont believe it, I have tried a couple of high rez renders and it seems to work, I need to test it on a few more renders but seems to be promising
cant thank you enough as I have a deadline next week so hopefully should be able to complete the job on time now.

Matb: glad I could help, I had to wait more as a year.

Thanks for the tip Bas Mazur , it works great!! I’m finally able to render in high res. Yeah!! ^^

@Bas Mazur : Aurick IS trying to help you but your confrontational attitude is certainly not the best motivator.

As for your rendering problem…
Increase the “Uni” value to 100. (It is located in the Shadows modifiers in the Light palette).
If this resolves your problem, then keep ‘Uni’ at 100 and hopefully this will not be an issue on your system when the next version is released.

Thank you, this is working.
I started this thread more as a year ago and time changed my attitude.

To date the best workaround I’ve come across is erasing or leaving the last scan line at bottom of render area blank. also have come across an earlier thread in subject about artifacts., I believe this is mostly a super sample effect and generally not noticeable in export.

WOW! After consecutive crashes, drawing a small zshphere in an easily “photoshoped-out” place did the trick. I guess Zbrush 3.2 for the mac has trouble rendering high poly geometry. Converting it to Pixols fixes that.
