Solve angle between camera and plane normal.
Hallo! I need help in writing script. So the idea is in testing angle between normal of a plane and FreeCamera viewing direction. I need to turn visibility of a plane off if angle is bellow 45 and above 135. I think the algorithm is something like that: angle between plane.1 normal and camera viewing direction >45 and <135, if true plane.1 visibility=1, if false plane.1 visibility=0.
but i really don`t know how to write it in MaxScript :(
