Take photo in game and save on pc

Hi! I’m using UE 4.13, in VR mode.

I’m using a SceneCaptureComponent2D and an i-pad to take photos of my environments.

Now, while in the game, i’d like to take a screenshot from the SceneCaptureComponent2D, and automatically save it on the pc.
Which command do i need to implement in the blueprint?
Am I doing something wrong?

Thanks for the help!
