I've tested it in several scenes (even with a default blender scene) and I always get just the same result: if I try to render the Z-depth image (Kernel type: Info-channel > Z-Depth) in Blender Octane Edition I get plain white image. At the sme time when I use "Rendered" Viewport Shading Z-Depth image looks fine. It seems like "Z-Depth max" parameter is being set to a value close to 0 during the render for some reason.

Strange but I'm rendering it without a problem. It renders the same in editor and in final render.
Make sure that:
  • - "Z-Depth m" parameter is set correctly – something above like 10 or so
    - Blender's Color Management is Off –> Display Device set to None, View – Default, Exposure – 0, Gamma – 1, Look – None
CPU – i9 13900KF, 128GB RAM, GPU – RTX 4090
System – Windows 11

Hmm, seems thet there's some EXR problem... If I choose PNG output, it saves fine.

In EXR it stores 2 channels: A (for alpha I guess) and Y.... and they are seems to be the same: Image

I see no difference when saving to OpenExr. Everything is ok.

This is really interesting. Try to turn OFF the Octane imager in camera setings and press F12 again.
