I recently purchased Carrara 7 Pro and I'm very pleased with it. Yesterday I created my first two objects in Carrara, which are very basic as I'm new to 3D modelling. They are simply a coaster and an empty glass. I think the coaster looks realistic but the empty glass doesn't because of the clear glass shader. I used almost the highest settings for rendering and it took my laptop about 12 hours to render a 1280x800 image! It looks good in my opinion but the glass shader creates a much too distorted, hall-of-mirrors-like effect. I'd appreciate it if someone would kindly tell me which settings I need to adjust to get a more realistic effect. Thanks. :)
