implicit scenegraph location is treated identically to the
volume location, with a few restrictions:
geometry.type: Only string values
volume(KtoA 1.1 / Arnold 4.2), or the custom Arnold node specified by
rendererProcedural.node(KtoA 2.0 / Arnold 5.0).
All other translation, including procedural arguments and arbitrary user data, follows the same rules. For more information please see the volume location.
