Hi,
i would like to reproduce a lot of sky-tracer spots with their volumetric light.
The way i found to reproduce the volumetric is an atmosphere with a VOP Lit Fog shader on it and a copy SOP for instancing my lights.

All works fine but i would like to include only my instance lights in the light mask of the atmosphere object.

Is there a way to define with the copy SOP, an attribute or something to the light mask atmosphere ?

Thanks.
