I’m trying to lit a wavy plane from behind in Eevee like in the picture above, but it doesn’t work. I thought all the settings for a common glass setup will be enough (transmission, IOR and the render settings), but the lit face of the plane doesn’t transmit any color or shining to the other face.
The environment lighting/texture are disabled to observe the pure light better:
The other face of the plane where the camera is placed is unaffected by light and looks dark. I need the plane to look like a lampshade, how can I do this in Eevee?
