HUD Position
The HUD (heads up display) is enabled in capture mode, and allows you to start recording a capture, name the capture and save the capture.

Depending on your game's setup, you may wish to change the position of this HUD so it doesn't overlap or block any gameplay or UI.
To do this, you can simply choose from one of the options in the capture tab of Luna Replay Settings.

For example, changing the HUD to be Lower Left would give the following result.

Alternatively, if you need to change the position of the capture HUD at runtime, you can use the HUD API.
