Working with Sequencer

When you have cutscenes to play, you can use the build-in blueprint node Play with an input parameter Movie Scene Sequence Player. To blend into and blend out of sequencer, you can set blending where it starts and where it finishes inside the sequencer. Or you can bind a custom event to Bind Event to On Finished where you explicitly call a camera with blending time.

For those of you interested in making sequencers, please refer to the official documentation Cinematics and Sequencer to learn to make high-quality cinematic content.
