Z depth and Environment Fog problems

[asboxerb]

Hello,

When I try to render environment fog, all objects appear at the same depth, around 75 units back from the camera. I guessed this was a problem with the z depth and checked the camera and rendering settings and everything appears ok. However, when I open an image with fcheck and press 'z' to see the z depth data, it says 'no z buffer.'

-Camera is set to output depth
-render globals are set to output z depth
-rendering in .iff format

To make things more confusing, depth of field is working. Does this not use z-depth data?

Any ideas?

Thanks,
Alexander
