In case you missed it, there is a link to do comparisons down near the bottom. Vue has a ton of new features that even Vue5 or Vue5PS can't match. I think the best feature for me is going to be the EcoSystem as this looks like it will make it a snap to create a fully populated scene, instead of adding an object at a time. Awesome! Also: "Export high dynamic range images (including skydomes)" This will be awesome for using as HDRI images in apps like Carrara 3+. These two features alone might make me side-grade. Wow. Very Impressive Stuff. Regards, PaulG
