Does Arnold support LPE group (object)?

[massa199734]

Hi there,

I'm looking for a solution to separate smoke objects in AOVs. Since cryptomatte isn't supporting volume yet, I see the LPE group is a possible solution (I saw that in Renderman doc).

I can assign a light group by typing the LPE light group name in each Arnold light. But I didn't see such an option in a geometry object, so I can create an LPE AOV like this: color lpe: C<RD'cube‘>[DS]*<L.'lightgroup'>.

Is that any solution to create an LPE group (not a light group) in Arnold? or any workaround solution (I have 5 volume vdbs, and I want them to separate in different AOV so I can make color correction in NUKE). Thanks!

Note: I'm a HtoA user.

Sorry, Arnold LPEs do not support shape labels
