Some highlights include:
Photometric Sunlight / lights
Grain system (to enhance realism of terrains and ground layers)
Nodal Function Editor (like Plant Factory)
This package is getting pretty impressive. Unfortunately seems like the vegetation animation capabilities (L-system type animations, grass generators, aging, seasons, etc) were all walled off and included in their Plant Factory app.
Anyone here use Plant Factory? Can you do some of the animation stuff you do in X-Frog with it?
