4 HeRo: Thank you.
This is how the glass turned out - probably will be in need of refining once all the model is textured. This glass material uses the bump and 'grime' maps made earlier with the 'grime' map being used in several channels of the material.
My personal favourite bit of this preview is the caustic pattern being generated by the sunlight passing through two items of dirtied glass. That's one of the nice things about Maxwell - you either have caustics or not with no endless messing about of settings.
I'm thinking making a start with a couple of 3d Shadow operatives soon to replace the tempory figures - once I've decided what to use to make them with. Either be modified existing figures or completely new ones.
