Hi, I'm posting as I've tried everything from every source I can find to get a successful z pass from C4d Octane without success and am now feeling pretty desperate.
I have adjusted the camera DOF Front blur and Rear blur accordingly as you would with a standard render (octane tag added of course). I then went into render settings and changed the Tonemap Type to "Tonemapped" whilst ticking the Z-Depth box on Info Passes. I select Tiff format at 16 Bit/Channel.
I then go ahead and render. As mentioned in many other posts, I just get a plain white tiff. I thought this would be remedied with the following tip in the official manual: https://docs.otoy.com/#60Extracting%20proper%20z-depth
Unfortunately this just isn't working for me as the "Extractor" effect in After Effects just doesn't find the Z depth pass in the plain white tif. All channels are empty.
I can't find any more information online on what I might be doing wrong so if I'm missing something, any help would be massively appreciated!
Just FYI the AO pass I render at the same time is working perfectly. Also I am on the very latest version of Octane for C4D R18.
