Check out e-on's site; there should currently be a program in place where if you purchase Vue 5 now, you get the equivalent version of Vue 6 as a free download when it goes gold. This is good for quite a few reasons. V6 has been retooled; it now uses a spectral atmospheric model, so you have true volumetric clouds and accurate lighting. You will also be able to import shader setups from Poser 6 to Vue 6 accurately (currently V5 ignores the Poser shader tree). There will also be reposing ability of Poser figure in V6 (the add copy says that -all- poser dials for a figure will be available...if so, then the morphs as well as the XYZ controls should be tweakable). As of Version 6, Mover is fully integrated into both V6 Esprit and V6 Infinite; no plugin to buy to use Poser characters in Vue. Then there is all the goodies like subsurface scattering, per object light generation, hypervoxels, texture and geometry virtualization (spooling them in and out of active RAM, to ease the memory load effect of large textures and meshes), Ecosystems 2 etc. If you want or need modeling capabilities as well as an end stage renderer, and if you grok the interface, you'd probably be happier with Cararra. If all you need is that end stage renderer, go Vue, and I'd recommend Vue6 Infinite; that way you get the entire feature set, including network rendering. Check out Phoul's V6 show video for an idea of what Vue is changing into with version 6. This one was done with a pre-beta version of V6I.
