The enabling sequence involves a lot of driven attributes within the scene. The thing I religiously practice is to create scene controllers that drive all the attributes remotely (I hate digging around for stuff even if I’m good with organizing everything within my scenes). Usually I use locators , grouped to host various levels of controls, parented to the camera I’m animating from. Personally I like that situation better than custom UIs because it consumes less screen estate. Below is the view of the connections involving the enabling sequence…..

There was also a lot of compositing involved in this project for more control and less re-rendering. Below are the passes and final composite for the introduction shot.
