How tu use the Zdepth ?

[TiRomain]

Hi,

I try to use the Zdepth with nuke, but it's totally different with the smoke pass.
I use Scanline Render, I check "Create Channels" and "Non Clamped Color" in the Fusion Works Renderer. In the renderer setup, I put the Color Range Limiting on scale.

I'm a bit lost.


Thanks
Romain
