Atmosphere Volume AOV

Is it possible to isolate the Atmosphere Volume environment shader into an AOV? I can't seem to find it in the included volume aov's.

thanks @Stephen Blair. I'm just going to make a seperate rop and matte vol out with geo. The speed difference is night and day. Is there maybe a way to tell arnold a volume is homogeneous? I feel like that is why atmosphere_volume is so much faster and standard_volume.

AtmosphereVolume uses legacy volume shading, and it doesn't support AOVs.

The recommended workaround is to create a big volume sphere or box surrounding the scene and using a standard volume shader instead. This also gives you some control over how far the volume extends and so how opaque it is.
