I'm trying to render just a depth AOV using Karma (Karma Render Properties LOP > Image Output > Ray Level Output > Depth (Camera Space)). However for certain scenes, the render comes out clipped to pure white, almost like an alpha mask. Sometimes I get the following warning:



I discovered that if I keep the Beauty AOV checked, thus rendering both a beauty and depth pass, the depth looks as expected.
Any idea why this is happening?

I'm trying to render my scene to a PNG image with only albedo applied, no other shading or lighting. I also want the background to be transparent (hence PNG). Similar to what the Marmoset Viewer [marmoset.co] achieves.

I discovered that the AOVs tab of the Karma Render Properties [www.sidefx.com] LOP allows you to specify beauty, albedo, etc. However, selecting the albedo AOV produces an RGB render with a black background. Only beauty produces RGBA renders with a transparent background.

Is an RGBA albedo pass possible without having to do any compositing? Previously I was resorting to a hack of turning off all shading except emission, and plugging the albedo textures into emission color. I feel like AOV is the "real" solution, correct me if I'm approaching this wrong? Thank you!

Got it, thank you!!
