'P', 'Depth', or 'UV' outputs in Karma seem to be broken.
'P' and 'Depth' outputs are well done in 19.5 version, but 'UV' output is not produced in both versions.

They work if you add them in the extra vars section. The checkboxes in ray level output don't set the aov format.

Yeh, 'P' is output in the extra vars!
But, how can I output 'Depth'?
It also seems like aov of vector variables is not working in Karma Material Builder.

You should be able to add it in the extra vars, there is a preset called "depth (camera space)"

Thanks, jsmack, it works alright.
But uv is output per polygon rather than per geometry with source type intrinsic, and none with source type primvar.

right, the ray:uv output is the face parametric. For the primvar, use 'st' or check your spreadsheet for the actual primvar name.

Thanks, jsmack. Using 'st' solved the problem.

Everything works well with the latest build of 539 except that AOV should be designated as Color not Vector3 in Karma Material Builder.
