Gweb, as mentioned earlier, C5 does not have a symmetry model function in the Vertex modeler. (Hexagon 1.2 does now) DCG plug Gemini can help with this for Carrara. The Carrara Vertex modeler is significantly improved by changing the modeling engine to Hexagon's. However, Hexagon is a better modeler with a more complete toolset. tkane, no tree animation at this point in time (but a slow camera pan can help disguise that) Carrara is really knocking on Vue'd door. The C5 volumetric clouds are better than anything Vue currently has. Vue still has a slight edge in environmental presets and richness of atmospheric editor at this point in time. As far as plants go, Vue has a very nice array of Stock plants that it ships with. However, the Carrara plant editor is much more powerful (not counting the motion capability of Vue) because you can actually add branches and leaves - you can't do that in Vue. The Vue plants do come with some excellent Alpha mapped textures for leaves and good textures but you can easily make those for Carrara plants too. There is no grass or small plant capability though Carrara yet - I wish there was. While you can create some excellent objects within Vue, the modeling in Vue is not as flexible or powerful as Carrara and there is no particle sytems either. Just the lunatic ravings of a madman here... ;)
