Now that we know how to create Matinees, we should be able to create amazing cinematics that make your levels really come alive! However, by default, when you play a cinematic, the player can still move around and turn. This may be the desired behavior depending on whether you're using something like a custom camera system, such as Resident Evil, or the Matinee for moving objects such as moving platforms. But, for a cinematic, we don't want it. Thankfully, there is a way to prevent this via Blueprints.
Before we start working, you should have a level opened and have a complete Matinee. You should also have it playing in the actual game. For assistance with this, check out the Playing a Matinee via Blueprints recipe.
