instance.type string Sets the instance type.
Optional. If not set, it defaults to object.
Note: Instancing in Arnold works by either
specifying an instance source location for
each instance, or by specifying an instance
ID, in which case the first location
encountered with a given ID becomes the
instance source for all subsequent locations
with the same ID.
If specifying an instance source, the
attributes under Instancing > Arnold >
instance apply. If specifying an instance
ID, the attributes under Instancing >
Arnold > geometry apply.
Instancing > Arnold > instance
geometry.instanceSource string Specifies the scene graph location of the
instance source.

geometry.arbitrary for specifying per-
instance user data overrides.
