I've been admiring some of the impressive images created with XenoDream for some time, but was unwilling to give up Bryce as my composing & rendering environment, so didn't take the plunge. But finally, as of a few days ago, XenoDream 1.5, which has a mesh export function, became available - so I bought & downloaded a copy. I've just barely started the tutorials & it definitely isn't as intuitive an environment as Bryce, but it is powerful & has a lot of preset shapes & functions that make it relatively easy to generate very nice models. I've been able to import several XenoDream models into Bryce & am very happy with the results so far. Here's a link to the latest image I created, that incorporates 4 such models: http://www.renderosity.com/viewed.ez?galleryid=843833&Start=1&Artist=eyeland&ByArtist=Yes
