 Extracting z-buffer from vray

This has proven to be a tricky thing to do. Here are some approaches :-

1. Try Bobo's channel extractor tool for extracting the z-channel from your RPF sequence. http://www.scriptspot.com/bobo/mxs3/channelextractor/ChannelExtractor_02.ms

2. Use 3D Channel Extract in After effects to render out the z-channel. You can animate the parameters to animate the point of focus.

3. Render out a fog pass from max.

Any other suggestions?

Hi re:Form;

I use VRay as well and I find using the fog feature works great for depth maps. You can also use the VRay override material checkbox in the renderer dialog to speed things up and then you won't have to apply new materials to all your objects - just drop it in the slot.

So that means rendering out the fog as a seperate pass? That would still be a pretty slow process in comparison with extracting the z-buffer directly from the vray g-buffers.

The new release of vray has better integration with max's render elements, so I will see how successful saving a series of z-depth bmp's is and get back to you.

Great plugin btw richard! Did you say whether you were working on a version that would utilise all cores of a multi-cpu system?

Thanks
Patrick.
