hey make trees, but apparently due to the programming that is unique to both, exporting would be something difficult My belief has been that they prefer not to have a bunch of non-vue users having great vue-generated gnarly trees in their poser/whatever program renders. Since their vegetation is better than most, it serves as an enticement to use their software (rather than aquire the output of their solid growth engine for use elsewhere) I doubt it has anything to do with complex programming. Just one cynical guy's opinion :) eric
