how to get the actual z value in zdepth element

[small61]

Hi guys

Seems the zdepth max is decided by the bounding of the entire scene?

Can I set zdepth max or set Clamp zdepth to false? Or it would be nice if the actual z of each pixel can be directly given.

Thanks

Yes, the Z-depth is normalized according to the size of the scene bounding box. There are no settings for it. We could easily print the size of the bounding box in the log though, would this help?

Not sure what you mean by that. A render element with the depth of pixels relative to the camera in scene units?

What is your use case, are you using Nuke or Photoshop or something else?

Yes, the depth relative to the camera. So if it is normalized by scene bounding, I can use app sdk to get it.

By "the size" you mentioned, is it the max value of the scene bounding?

My use case is to do some post processing by depth.

The maximum depth is taken from the largest component (X or Y or Z) of the diagonal of the axis-aligned bounding box of the scene.
