@Erlik- Oh no, I haven't  forgotten about Poser6! DAZ has added these capabilities in order to be more competitive in going head-to-head with Poser6. And Carrara just added wind animation to its trees, probably because Vue Infinite already has it, and animators want that feature. I disagree that Carrara's terrain capabilties are bad, they're just different.  And I'd sure as heck rather build a landscape in Carrara than in C4D, LW, Maya or 3DMax(orXSI) cause at least Carrara's got a built-in terrain and tree lab.

However,I will readily admit that I still find Bryce's terrain lab much easier to use, though that may be because I have used Bryce a long time and am just starting with Carrara5. One big difference I've noticed though in Bryce's favor, you can animate terrains in Bryce, but you can't do this currently in Carrara.  Maybe Carrara's ability to utilize an animated displacement map makes this a moot point. I still find it a lot easier to build a scene or landscape in Bryce, but when I build a scene in Carrara I have a lot more options for rendering and animation, which is a keen interest of mine.
