[Bf-committers] Raytracing - Hollow Sphere problem

[Alexander Ewering]

Hello,

it seems that nobody ever tried to render the simplest cliche object in
existance with raytracing: A non-solid glass sphere!

The correct way to model such an object would be to make a sphere, extrude
and scale it inwards a bit, and then making the outer faces point outside
and the inner faces point inside.

I did this, and I got a black render, OR a render that definitely had wrong
refraction.

How is this supposed to work?

Thanks :)
