Help needed with z depth pass.

[Gumz]

If I change kernel to infochannels/z-depth and play with the z-depth max value, I can get a nice usable depth map that I can save from the live viewer.
I can only do that with still images. For animations I obviously have to use render passes. If I copy the z-depth max value into the render pass settings, all I get is pure black and white image, kinda like an alpha channel pass. It doesn't seem to matter what value I enter in the z-depth max. Does anybody know what's going on?
I'm using v.3

It's linear in PV, tonemapped in LV. Linear means that results are in range 0-ZMAX value not in range of 0-1.

if you are rendering out EXRs its all there. Just import into AE or Nuke, make sure 32bit per color is activated and exposure the picture DOWN until you can see the depth

Oh yea! The map magically appeared when I switched to tonemapped.
Thanks buddy!
