From the features list, Vue 5 is going deeper in existing features rather than adding new ones. I'm intrigued by the "materials editor".

If the HDRI and radiosity features are good then my copy of Carrara will be going on eBay. :-)

These features are very advanced and for a domestic package, the price is a bargain. I suspect my rendering times are going to increase substantially but the quality improvement should more than compensate.

Cheers,
Mark
