[Opensim-users] creating bots at negative elevation

[Gudule Lapointe]

Call the police ;-)

In my viewer, the region settings show, by default:
	- water height	20
	- terrain raise limit:	100
	- terrain lower limit:	-100

These are the default values, I didn't change them, so I guess it's not "illegal" to go under zero… Or is the terrain lower limit based on something else than elevation?

Though I admit it's odd to want to go so deep, I understand it's needed for a big under-water project like Titanic….
(the only work-around would be to change water elevation, which would be quite odd for surrounding regions)

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.
