Vue's plants are created in SolidGroeth, a proprietary system peculiar to E-On's software. Vue Pro has an editing system but allows customisation of existing plants only. Vue 4 allows changes to mapping and nothing else. I've found SoldidGrowth render times in Vue 4 are not that much quicker than imported 3DS plant models. One reason I opted for Carrara 3 over Vue Pro is the former's plant function the options for which are staggering. More sleep lost in the coming autumn months ;-) If Bryce is really dead, then Carrara and XFrog offer the only affordable ways to make editable plants, from scratch, at reasonable cost.
