Sorry about the 'hijacking'. One thing that is clear is that for most users no 'environment modelling' functionality, even with smart coding is ever going to replace the craftsmanship of the experts. Now if we Studio could combine batch rendering with 'make art' (NVIATWAS) functionality to create a slide show, it could be marketed as an executive screensaver ;-) Whoops, still hijacking, I'm afraid. -- Bill (who's sitting in an office that probably was randomly designed by an extremely unimaginative piece of software).
