Well not bad.
Unity have also a user made system allowing put textures directy on terrain (texture projection).
Very usefull to have very fast simulated shadows !
The object tool allowing a group of objects to adapt to terrain
is a simple variation of grass editor.
you can also do already that in Unity just by changing the meshes : Use stones instead of grass on a new brush object for terrain
I see nothing that would make me buy it , nothing really new !
But a good alternative for people that would not want Unity or Torque 3D or simply for A8 users that don't have such world editor
!
Why don't they put a real demo to see how such scene would run on standard PC ???
