I have the report in to the P12 devs (via GitLab).

Bearing in mind that my machines are Win7, so your results may vary, I've found that sending an animation to remotes via Queue successfully produces the Z-depth maps and Normal maps if you render in Superfly. But, the Superfly menu does not offer toon ID.

In Firefly, I get no auxiliary data maps (I had toon ID, Normal, and Z-depth selected).

Poser 12, in feet.
