lets say I have a triangle at 0,0,-1
and it’s normal is 0,0,1 now if I have a light source which is on the other side i.e. (z<-1) would the lighting properties be calculated correctly for the other face of the triangle? or do I have to do some special stuff to enable it or something?
And yes, I am aware, that with the current position I will not be able to see the back face of the triangle. I meant, if I was teleported to the other side, and was looking at the back face.
