As of Rhino 8.6.24101.05002, I’ve been unable to get ShowZBuffer to do anything. Have been trying for a few Rhino updates.
I create some sort of basic poly surface (e.g. Sphere), initiate the command and the only thing I’ve noticed happen is for the ground plane to disappear when viewed in rendered mode. In other modes (and all viewports) I can’t even tell whether the command is on or not.
Is anyone else having the same problem? Is it a bug in Rhino 8? Am I doing something wrong?
Hi Ray -
I see that here as well → RH-82309 ShowZBuffer: Does nothing when running Metal
Thanks,

Admittedly, read without the accompanying sentence it does imply that. Better if I phrased it when I encountered the issue (only just having discovered the command) I was using v8.6.
I see this too … running ShowZBuffer does not do anything on Rhino 8 for Mac (8.13)
Hi Luke -
It’d be somewhat worrisome if this worked fine on your system. RH-82309 is currently still open and on the 8.x list.

Indeed @wim 
For the record (and if anyone else is stuck until RH-82309 is landed) I discovered you can use the Render command and output the distance channel to get basically the same effect!
Yup. That’s what I ended up doing too. Although from memory it wasn’t as good (might be wrong about this) but does the render automatically scale from 0.0 to 1.0 to match the closest to furtherest points of the model?
