Hello there. Here are presented series of screenshots (low resolution) of the second section with commentaries. Take a look.
1 - The character model itself is a Blueprint. Little comment - model is possessed due to begin play action, which means when the play start - player possesses the Character in World.
2 - Sun Direct (Light Source) - half lighting work is proceeding through its parameters.
3 - Trigger Volumes. "When the monolog starts". Written in Level Blueprint
4 - Level sound effect. That one buddy who makes an ambient presence effect noise on level.
5 - Appearing\ disappearing Text. Works when triggered once. Blueprint made.
6 - "Nature" wind effect. Optional, of course. Have many options in detail panel.
7 - Sequence which starts on BeginPlay Event, optional as well. Might be put on trigger vol.
8 - Light pillar. Actually here you may see a few objects (actors), but in Level presented as one Blueprint with sensitive to each other's components. (Screenshot attached)
