FindLookAtRotation — rotation from Start point looking at Target point

Returns the Rotator needed to look from Start toward Target. Common for aiming and facing.

FindLookAtRotation — get rotation to look from Start toward Target

Line trace from camera to detect what player is looking at

Pattern: GetPlayerController → GetPlayerViewPoint(outputs Location,Rotation) → GetForwardVector(Rotation) → Multiply_VectorFloat(A=Forward, B=TraceDistance) → Add_VectorVector(A=CameraLocation, B=Offset) → LineTraceByChannel(Start=CameraLocation, End=TraceEnd). GetPlayerViewPoint exec in='execute', exec out='then', outputs: 'Location' (Vector) and 'Rotation' (Rotator).
