This was probably the mistake.
The other handlers are named RenderMaterials as well but this actully has no affect apart from on stats, due to a (counterintuitive) disconnect between the registration name and the name of the request handler.
Will be tested very soon and reverted if this still does not work.
This cannot be triggered as an event from Scene.EventManager since some invocations of UuidGatherer (e.g. IAR saving) use scene objects which are not in scenes.
There needs to be some way for modules to register for events which are not connected with a particular scene.
This is in order to reduce the likelihood of naming clashes, make it easier to filter in/out attributes, ensure uniformity, etc.
All dynattrs in the opensim distro itself or likely future ones should be in the "OpenSim" namespace.
This does alter the underlying dynattrs data structure. All data in previous structures may not be available, though old structures should not cause errors.
This is done without notice since this feature has been explicitly labelled as experimental, subject to change and has not been in a release.
However, existing materials data is being preserved by moving it to the "Materials" store in the "OpenSim" namespace.
