I purchased Vue 6 inf and like the way it works, no problems here. There are other apps that do almost the same thing in some cases better (Worldbuilder 4 pro, World construction Set 6 Carrara 5 pro) If you feel the pricing is unfair check out some of the other guys.

On that note how come there aren't more people using Worldbuilder, I got a free version 3. something off a mag and it is a great program, one of the features I like is its shoreline water it does it in layers and you can also define where the textures are placed by drawing the area where they go.
