Ok, so I'm trying to render a scene with a Depth Map so that I can convert it into a hologram.

I just can't get the Z-Depth option to work - the normal map and texture co-ord maps look fine but the Z-Depth map looks like a simple mask: pure black and pure white and no in-between.

I don't have a skydome, I even turned the ground object off in case that was messing with it. I simply have a V4 figure and a few lights.

I added a primitive cube in the background to see if that would change anything but nope.

My Focus distance is 5.75 so I reckon start should be zero and end should be below 10 in terms of distance (I tried using an atmosphere with depth-cue turned on to no avail also).

any ideas?
