One of the things that I am a bit disappointed about is Vue's plant editor. There is one, but it is fairly limited: it will let you alter existing designs, but you cannot design completely new shapes with it, and if you want alien forms, you need more freedom that Vue gives you. Of course, there is XFrog: it will allow you to do that, but it is difficult to learn and for several years now all development efforts have been directed at versions to be used with major 3D packages, leaving general users like me with the 3.5 version, that is by now rather old. Still, you can design very interesting shapes with it.
Animation is another subject that Vue must be able to do, as there are breathtaking demonstration videos available, but unfortunately most general users find it extremely difficult to get good results. In experimenting with animation I was not too disappointed, but my standards for animation might not be that high. It is possible that the latest version of Vue is better, but I am at least one version behind.
So here are two scenes from a very quiet swamp. The reasons it is so quiet is twofold: I should add some sounds, but I have never create an alien nature sound track yet. I do have ideas on how to do it, but it does not have a high priority. The other thing you will notice is that the plants and the water do not move at all. Vue can actually produce plants that move in a breeze, but that works only with its own type of plants, not with imported objects.

You can find the same swamp in the plants section by the way.

You may well find that the scene isn't that alien, and you would be right. I am guessing that branching plant shapes would converge in design across the universe, but I could have thrown in a few mixomorphs or ballooning plants to spice up the scene. Then again, there are items you cannot see that well. The 'spirflower' is a case in point. Flowery things are probably universal, in that it makes sense for sessile life forms to entice mobile ones to help with procreation. A flower is just an advertisement. There is no need for them to look like Earth flowers though: any form might do, I guess. The spirflower has two brightly coloured blade-like leaves in a double spiral, with small bulbs on top that exude the reward for landing there (while secreting some sexual cells, of course). Here is one in a close-up, done with Vue.
