I hope this is the right forum.
Does anyone knows how to tell blender not to render back faces, to render only the faces with normal facing the camera and the faces inverted, not to render them or render them completely transparent?
For instance, if I flip normals of a cube and use this option, I would see only the faces on the other side of the cube, not the ones in front of me.
Or if I use this in arquitecture, allowing me to see what is inside a room from any angle, even if the room is completely closed.
And, another question that could also solve this, but that is a question by itself; is it possible to apply to different material to a face, one in each normal?
Like a paper of a book, so I would have one text in one side, and other on the other. Or, in this case, I could have one texture transparent on one side, and an opaque texture on the other.
I really appreciate any help. This is quite urgent for me. If this is not the best place for this question, please, help me ask it where I could get help.
