How can you tell if a 3D point is on screen in VR?

Is there a way to detect if a point is on screen in VR, preferably in a blueprint?

Normally, I'd use the ProjectWorldToScreen node to get the point's screen coordinates, and the GetScreenResolution node to get the max coordinates. For some reason, that doesn't work in VR.

I 'm running with a VR preview window open.
