I made most of my wall 3d assets as planes but i noticed that the light goes through the black/useless part of the plane, therefore the wall is not casting any shadows, nor the roof
Cast shadow is enabled…
How do i fix this?
a plane by definition has no depth, so only one side is rendered meaning only one side can block light. to combat this there is two solutions: give the plane depth (make it into a cube like shape) or set your material to two sided.
