I did also a sphere in two forms planes and rounded form.
I would like to ask you about:
1-Why the brightest planes in the sphere is at the left sides of the sphere if the light direction is three-quarter?
2- Why in the rounded form there is no Turning Plane that we usually add at the edge of the light side?
3- Why there is highlight on the sphere if it looks like a stone which the stone supposed to be Matte Surface, not refletive!
