Animation Map Export (BPR Render passes) ?? (answered)

ZBrush Usage Questions
#1

Hi,

I have a couple questions hopefully someone can help me with.

First, I’m planning to render a good chunk of my demo reel straight from Zbrush, and would like to be able to do compositing of the render passes externally. Is there anyway to export all the render passes of an animation as separate images? Or is the only way to render in Zbrush turning on BPR, rendering out the animation, then exporting as a .mov?

Also, is there any way to render only certain frames of an animation? Say 20 frames at a time, so I can render at nights, or on multiple computers at my school? If it’s an all or nothing ordeal this might be complicated. Letting my home PC render for 2 weeks doesn’t sound like fun.

Thanks,

~Sean

Currently the only way to render out a Timeline animation is through the Movie palette, exporting as a MOV file. With Quicktime Pro you can split this into an image sequence.

An alternative is to use a beta version of Turntable Plus for ZBrush 4 which I posted here:

This doesn’t offer as many options as the Timeline but you can use the BPR maps and if you set things up carefully you can render in small chunks.

thank you much Marcus. I do hope this will be implemented soon. In the meantime I can render out some of the passes with timeline, mainly an alpha pass using the flat shader and filling the model with white, and using that a luma matte in after effects. I was just hoping I didn’t have to do that :slight_smile:

what compression does the .mov export in the movie palette use? is there much loss of quality?

You can specify the compression codec and the quality. What’s available may vary with your version of Quicktime - I can export with no compression.
