Scenes are not lighting cues. They are recorded XYZ positions of objects, so in a sense you could think of them as Acts. In Act 1 for example this object is positioned stage left, and in Act 2 it is positioned stage right. Applicable to cases where there is no motion controller altering the position in realtime, but rather when stagehands alter the scenery in between acts. This way you do not need to have multiple capture project files to depict your entire theater play.
If you are looking at altering the light settings and replay them then you can do that by recording snapshots and snapshot movies, which can also recall the above mentioned scenes.
