HTOA Arnold 5 Depth - Empty Areas of Frame at Far Camera Clip

[nickchamberlainvideo]

I'm trying to render a depth pass, and I'm having an issue where the empty areas of frame are being filled with the value of my far camera clipping plane. Is there a way to make the empty areas of the frame black?
I've attached a test image showing the white bg at a value of 50000 (current clipping plane).
Thanks!

That is by design. The Z AOV uses the far clipping plane for areas where there are no objects.

You could build a custom depth AOV:

• Get shading point in world space (state vector)
• Transform to camera space (space transform)
• Negate/complement to get positive value
• Write to float AOV

But if you have a skydome visible to the camera, you'll still get non-zero values for empty areas.
