conserve_energi is only needed when you have transparency AND reflection.

It's usual for the reflected part to not be as sharp as the incident beab.

The specular and roughness have nothing to do with reflection, the affect 
specular highlights. They do the same as phong/phong_size, but with a different 
model.
