Is per light AOV with volumetric effect possible ?

I want to render our per light AOV with volumetric fog effect.

But the volumetric light are in the emission aov category (with all lights).

Is there a way to separate each light with volumetric fog ?
Even if I check light group in the emission aov , it does't show up in the render.
Has anyone done this before? so frustrating right now.

Per light AOVs are not supported with the atmosphere_volume, it's a limitation at the moment. The workaround is to use a scaled Arnold Volume in Box mode around the scene. Than you can enable light groups for the volume AOVs.

Hello,

What about now? Is this limitation corrected already? @Peter Horvath

No. atmosphere_volume still uses an older volume system, and light groups don't work with that older system.
