Not Done Inline ActionsSince this geometry set might be part of a "tree" of nested instances, it might have an instance component that contains more points that could be converted to volumes, so keeping GEO_COMPONENT_TYPE_INSTANCES is necessary here too.

Not Done Inline ActionsUsing the same vectors for all geometry sets (there might even be multiple threads working on different instances at the same time) likely won't work. They should be declared in the modify_geometry_sets function. Actually, I would recommend moving the modify_geometry_sets loop to the caller, so this function only needs to worry about a single geometry set, that also makes sense since the caller is quite simple currently, it can handle doing a bit more.

Not Done Inline Actionsvolume is just a raw pointer, so moving it doesn't have any benefit. HooglyBoogly: `volume` is just a raw pointer, so moving it doesn't have any benefit. | |||||

Not sure if this was a problem before or not, but the new node can use PROP_DISTANCE for the radius too.
