Rendering crash on Mac

ZBrush Usage Questions
#1

Hi All,

Okay, I am very new to zbrush and just working my way through the basics. I have been planning on rendering the same tool with a variety of different textures n the same position on the canvas and then compositing the image in Photoshop via layers, masks, etc.

The problem I have run into is that I am getting crashes as the render is finalizing. The document size is 4029 by 3029. I’m trying to get around 10 inches high at 300ppi.

Regardless of the material, and it doesn’t seem to be tool specific either it crashes the majority of the time just as the rendering is finished. I am using the best render setting and leaving everything else set to the defaults.

First I thought it was a bug with version 3.2. So I saved the tool, imported it into 3.12 this morning and I was able to render once successfully. However, latest attempts result in a crash. I am puzzled as to shy it worked once and will not work again.

Any ideas? Could this be a memory issue? Is htere a way to allocate more memory? I have 6 gigs on my Mac pro.

Any ideas or suggestions would be greatly appreciated.

Thanks,
derek

It’s probably just running out of memory. You may have 6GB of RAM, but ZBrush is still only a 32-bit application. I’d suggest closing down everything else to free up RAM, and maybe dialing the resolution of your render output down a tad if you can. Just experiment until you find a size that you’re able to render reliably.

Thanks. I’ll give it a try.

Also wondering if it would be easier on the memory to drop the tool to the canvas first.
