…over Fixes PixarAnimationStudiosGH-3395. As described at https://openusd.org/docs/api/class_usd_geom_point_instancer.html#UsdGeomPointInstancer_protoProcessing PointInstancers can define prototypes under a parent prim specified as an over. The ComputeExtent plugin registered for PointInstancer was not correctly computing prototype bboxes in this case. This extends UsdGeomBBoxCache to allow for a custom prim predicate to be passed, which the updated ComputeExtent plugin takes advantage of to traverse prototype prims in this case.

There was a problem hiding this comment.
I was a bit unsure about this change. Looking at where this is called, it seemed to me that this should be following the same predicate as the other traversals, but it was not before. Let me know if I need to roll this back

I took a stab at addressing this, but let me know if I went down the the wrong path |
