HdGpGenerativeProceduralResolvingSceneIndex is a scene index which evaluates prims representing generative procedurals within its incoming scene and outputs their resulting prims its own observers.
The hydra prim type used to identify generative procedurals can be configured per instance of this scene index to allow for a pipeline to stage when certain procedural prims are resolved within the chain of scene indicies. By default that type is "generativeProcedural".
This scene index also re-types (to its observers) any procedural prim it acts upon to be of type "resolvedGenerativeProcedural" to avoid potentially evaluating a single procedural multiple times.
In its current form, it does NOT recursively resolve any procedural prims which are the result of the procedural prims for which it is itself evaluting. Additionally, all procedural prims evaluated here see the same input scene – and not the results of other procedurals resolved by the same scene index instance.

Returns the paths of all scene index prims located immediately below primPath
. This function can be used to traverse the scene by recursing from SdfPath::AbsoluteRootPath()
; such a traversal is expected to give the same set of prims as the flattening of the scene index's PrimsAdded
and PrimsRemoved
messages. This function is expected to be threadsafe.
