Primvar inheritance into multiple-instanced prims

Community Hydra

Are there any special things that must be done in an Rprim to get inherited primvars ?

my only re-creation case is some horribly crusty file that has multiple levels of instancing, but I don’t think I’m getting primvars:displayColor inherited down from an Xform into a Mesh.

Storm does a bunch of stuff in DrawItems to get the primvars, so I’m thinking I need to do something, but not quite sure what.

I also feel like there’s some handling of this kind of thing in the Instancer classes, but nothing is leaping out as “oh, call this”

any pointers ?

@Doug.epps I think there’s some issues getting primvars:displayColor to inherit since it’s specified in the Gprim schema. Does inheritance work as expected for other primvars?

I’m .. not sure. transforms are. But I can’t make any per-instance primvars work. But at least some of that is on my end.
What’s the (I assume in the Instancer) idiom for getting per-instance primvars ?
