Shell Modifier in 3dsmax
Many of us would have faced the problem of polygon flipping while importing .3ds or .obj files. In this tutorial I am going to simulate the polygon flipping scenario and a way to rectify it. The Shell modifier in max is useful in achieving this. Polygon flipping is basically the direction of normals facing the other way. So usually when you draw a plane in 3dsmax viewport, you can see only one side of it, the other side becomes invisible.
