I had a look at the greenhouse you designed, it is a great work.


With my 3D model, I still have a too much mirror effect on the surfaces.

When the surface faces the camera, perpendicular to the camera direction, there is a few mirror effect. But the more the surface is mear to be parallel to the camera direction, the more there is a mirror effect.

I tried to set d value to 1.0, and there was no mirror effect at all. But, for a d value of 0.99, there is the mirror effect.
