A couple of renders using a modelled bell jar, which I created with Wings3d and Blender…. Also a 3d scan of a head! All rendered with Toolbag3. The first render was not quite right, the refraction of the glass and dust/grime needed tweaking which you can see in the final render!

The second render is a real improvement indeed; especially the muck /condense on the inside of the jar and the light coming in through the open door.

Thanks Andy! The head was from ten24 – a freebie… I tweaked the shaders a bit, amazing detailed scan! Glad you liked the glass and grime!
