I’m not 100% sure if that will get you the entire effect you’re looking for but try to just get rid of the “AxisEvent LookUp” and “AxisEvent LookUpRate”.
Those handle the player input for up & down. Deleting that code should disable the player from changing the angle of the camera.
Setting it up at the angle you want should therefore lock the camera at that angle.
Try that out and if it does something wrong please to reply with what’s going wrong and I’ll take a closer look at what’s going on in engine.
Cheers!
