How can I get a Z depth map in Blender? When I connect the Z pass to the image Viewer Output I always get a completelywhite image. I’m using 2.63 . I’ve tried using the Depth of field option on the camera. The depth of field with the defocus node works with the Z-depth. But it doesn’t show when I try to output it as an image. Can anyone help?
I want something like this:
The info is in there, try using a math node to ‘pull it out’. Like this… 
Edit: Yes, it’s good to insert the pic too, hehe… ;D
Or simply a Normalize node. 
No no no, the normalize node inverts the phasing of…
Just kidding. Didn’t know of it actually… I guess it takes min-max values and remaps them to 0-255…? ;D
anyway I can get the z depth with smooth edges?
Render at 3 times the wanted size, blur just slightly & scale it down to output size. At least this is what I’ve done in MentalRay having the same issue. Depthmaps are always aliased. 
thanks guys! The Normalize worked! Cool!
You lost me there Farmfield. I got the techno-babble, but what about the min-max values?
