I'm having some trouble with light linking on pointInstancer. Should the link be made on the prototypes or the pointInstancer primitive? Every combination I've tried is producing results I cannot fully understand so I thought I'd ask what the recommended procedure is or if this is something that is not supported by USD.
I would expect it to work only by linking to the entire point instancer prim, but sometimes details like this slip through the cracks so I also wouldn't be terribly shocked to learn that there are some bugs around this.
