What is the puspose of Distance Render in Bryce? I saw in the manual that , that is how you can do focus blurs by importing it into the Alpha channel of the image you want. But i can not seem to figure it out, If anyone knows some ideas to help me that would be great. Thanks!

I think the idea is to use the distance render as a mask for a gaussian blur in an application like Photoshop.

They are used primarily for landscapes. First render your scene normally & then render the distance render. This makes a grayscale render with closer terraine darker. Then open your normal scene in Photoshop (or similar app with layers), create a new layer and fill it with a color that you want to be your "haze" color. Then add a layer mask & paste the distance render into it. It will diminish the "haze" color from the foreground to backround according to the levels of gray. Havn't tried the "blur" thing from fore to back however.

It can also be used to create nifty black and white art. See http://www.pussreboots.pair.com/art/beachfun1distancesm.jpg for an example. Sarah
