Auto Add to Sequencer
You can automatically add objects to Sequencer when dragging them into the viewport from the Modes panel or Content Browser provided you have a Level Sequence open.
Ctrl + Drag asset into viewport
This will automatically add the object to Sequencer.
Shift + Drag asset into viewport
This will automatically add the object to Sequencer as a Spawnable.
You can also drag assets directly into Sequencer which will add them as a Spawnable.
When dragging in the Camera Rig Crane or Camera Rig Rail assets from the Modes panel with either method above, a Cine Camera Actor will also automatically be created and attached before adding both to Sequencer.
Additionally, a Camera Cuts track will also automatically be created in the open Level Sequence and the new Cine Camera Actor will also be assigned which can be a fast workflow for setting up a shot with the crane or rail.
