A very powerful programme with animation facilities for just about everything including the movement of grass. Not as realistic as some of the programmes yet but a new version is due very soon.There is a steep learning curve and many of the functions are not as intuitive as they could be. A new version (v4) is due out in the next few months. This will be a major upgrade
There are quite a lot of basic trees, plants etc are supplied with the programme and they are extensive possibilities to link with Max and Lightwave.
