Ok I have been trying to find out why I should not use non-manifold faces. I under stand that you should not have any non-manifold faces for 3D printing. Is it ok to use non-manifold faces models in a game and what problems do non-manifold faces give I am finding it really hard to find info on this. So I am grateful for…
I believe the non-manifold faces like this shouldn't be a problem: However, faces that can result in invalid triangulation are sometimes referred to as non-manifold as well. For example the red polygon here: It can be triangulated either like in the middle, which would be fine, or like in the right , which would result in…
