[Opensim-users] creating bots at negative elevation

[Gudule Lapointe]

(JCC: Having seen the project, I know this is not "under the ground", but deep in the water, which goes far below zero level, due to project needs…)

I wouldn't be surprised if NPC was just coded without thinking somebody would try to do this ;-)

Paul, I would suggest using the NPC sit functions on an object at the desired position (http://opensimulator.org/wiki/OsNpcSit) to force the NPC go that deep, and after that you are free to make it stand or stay sitting…

ScenePresence.CompleteMovement(), which is how the NPC (and any avatar) enters a scene does have code to prevent attempted rezzing below ground.  This is just using a 1.5f constant.  It's possible that if you're very near the ground then you would have a problem.
