I must ditto what Amir (casamerica) said above. Vue's version 2 is outstanding. I started using Vue with that version, and found I could do pretty much anything I could think of. The interface and controls are very intuitive, so much so that you'll hardly need the manual at all. But if you do need it, Vue's manual is excellent and contains many easy-to-follow tutorials. Vue is currently in version 3.1. Version 4 is due soon, which is why (I assume) they're letting v.2 go for free now. :) Varian --Treasures d'Esprit http://www.varian.net/dreamview/dreamtools/vue/ Models, materials, atmospheres, tutorials and more for Vue d'Esprit users
