Unreal Set a Speficic Camera to Active in Level

How to make the Camera in the level to be activated when the game start.

Set the Camera in Your Level to Possess Player 0

Here's a breakdown of the process:

  1. Locate your camera actor: In the Outliner, find the camera you want to use as the default. 
  2. Open the Details panel: Select the camera in the Outliner, and the Details panel will display its properties. 
  3. Find the "Auto Possess Player" setting: Navigate to the "Auto Possess Player" option, usually located under the "Rendering" or "Actor" section. 
  4. Set to "Player 0": Change the "Auto Possess Player" setting to "Player 0". This means the camera will be possessed by the first player when the level starts. 
  5. (Optional) Disable other cameras: If you have other cameras in the scene, you might want to disable their "Auto Possess Player" setting to avoid conflicts. 
  6. Play the level: When you start the level, the designated camera will be active.
