Making sense of sensors

I have a prim that's got a sensor in it for a named object (prim). If that object is rezzed on the ground in the vicinity of the sensor, all is well. If, however, the named object is attached to some body part of an avatar, the sensor seems to not be able to find the object. The sensor is in "passive" mode with a range of 20 and arc of 2Pi. Any ideas what I have set up incorrectly that is keeping the sensor from sensing?

Essentially the problem is that attached objects are much like child prims. A sensor will only find objects, rather than the objects' individual prims, and in the case of avatars, will only find the avatar and not its attached objects.

Depending on the application, you probably have plenty of ways to work around it (:

Speaking of sensing attachments, does anyone know of a way to detect the attachments someone is wearing or has on as a hud?

I know there's no way to detect what item is emitting particles, even often even who is holding it, but being able to figure out who is emitting massive amounts of particles would help a lot in stopping certain kinds of griefing.

Not with a scripted object, unless the attachment is doing something detectable to give itself away.

Coming back to manual work: When particles strike, my drill is:
1. You may press Ctrl+Alt+Shift+= to hide particles
2. View > Beacons > Particle Sources
2.5. If necessary, View > Beacons > Render Beacons. Beacons may be alot easier to see than highlights
3. View > Beacons Always On (Ctrl+N)
