Shading with an animatedsprite 3d set to billboard

Godot Version

Question

I have this character billboarded to face to the camera, and I was wondering if it was possible to make his character darken when facing away from light blocking the camera from it like in this image where he is pointing away from the light source. additionally, I would like to incorporate normal maps into this shading as well if possible.

If you enable shaded flag for the sprite, it will react to light even if it’s billboarded.
