When you say scene transition, do you mean teleport the character to another level? or another place within the current level?
Here's a post I made on using objects to teleport you around:
http://larian.com/forums/ubbthreads...s=onuseaction&Search=true#Post615299It's not super detailed but the gist of it is you need an "OnUseAction" set to "Teleport"
You need a point trigger on the other end (made global if in another level). In the OnUseAction - Teleport you pick the trigger you want to teleport to.
It should work straight off if it's all contained in one level.
If you're going to another level, make sure to generate definitions after making your trigger global.
