Rendering Z-maps

Recommended Posts

Hi all,

It's been quite a while since I have been here. I have spent the last year learning different sorts of skills, but now I am back to work with Houdini. Can anyone suggest a method for rendering out z maps for compositing? I used to know of a work around for Houdini to generate these, but it's been nearly two years since I have done so. Could someone refresh my memory please. Thanks.

Hey Grav--

Long time no see! How's life treating you?

And for a simple z-depth pass, if you don't mind it being in an extra raster/channel, you can simply go to your Mantra ROP, click the 'Deep Raster' tab, then for the 'Variable Name' box click the pop-up list and select 'Pz (Surface Depth)'. Voila - in addition to your RGB channels, there will be a fourth Z-depth channel.
