Is a UV Sphere with a glass shader applied to it considered to be a shell of glass or a solid sphere of glass in Blender Cycles?

Just to illustrate how Cycles treats these cases: Left: Sphere walls with zero thickness (light refracts twice) > behaves like a solid glass ball Right: Sphere walls with 1 mm thickness (light ...

How do I make imperfect window glass?

A (maybe too elaborate, 'classical') pure-procedural approach might be to split your texture-space into tiles, using a Wrap node: Below: original UV on the left. Wrapped UV ('Cell UV') in the middle. ...

Glass casting shadows and not looking real
