I have a plane that I divide using knife in some faces.
Using nodes, I Apply a material to each side of the face.
I want to know which side of each face is being captured by the camera?... I mean, which side is being rendered?
Actually, I tried to capture the order of the vertices of each of the faces, the normal of each face, try to get the Reversed faces because have a negative dot product value and many ideas!., but nothing work.
do you know some solution?
