I'm building an interior scen consisting of a room with four windows, see image below. Behind the four windows, on the outside I have a plane with a background image to get a nice view from the camera. The light in the scene comes from a Hdri image.
But I guess the plane prevent a lot of light to enter into the room because of the plane? Is there a way hide the plane for the Hdri light, but still be visible for the camera?
