The Lighting Controller

3d view only works correctly if you start form the beginning of a timeline. The problem is, I'm working on the last 10 seconds of a 4 minute piece, and don't want to play the whole timeline every time just to see if the lights look good in the last ten seconds. Why is this happening, and is it possible to correct this?

If we right understand your problem, this is because, in order to play the scene correctly in TimeLine, the scene must be triggered from its beginning. We can not change that ; TimeLine only triggers the scenes ; it does not timecode them.
3DView has nothing to care with this problem.

Ok, then wouldn't it still trigger the scenes as they come up? For example, if I start it in the last 10 seconds of a song, the scenes that are on the timeline after that point should trigger. However, this is not the case. No scenes will trigger unless I start from the beginning.

The scene always triggers, but it always starts from first step.
