Does look good.
I agree Confusoid. I was thinking of trying to work out something similar within the population node and object textures. But at the moment I'm still grasping at the basics of TG2. I don't think it would be beyond the capacity, because something I've always noticed with TG2 populations is the lack of variety within colours. It would be good if you could select a number of objects to fill one population, then to procedurally affect it's variance. ie, several variations on a species model, and applying a fractal colour shift, without having to set up new populations. But maybe I'm jumping the gun here a little.
I also think a possible optimisation method maybe to set a canopy depth as well as a population perimeter depth, so that un-needed geometry can be ignored, to speed up renders. Again stuff for PS to think about.
The problem still remains with this plug-in and TG, is in getting those lovely procedural textures and landscape geometry into Max, and even then you are missing out on TG atmospherics.
Moodflow. Got to say it's the best I've seen yet animated, although I think the sun position helps that demo animation hide a lot of possible sins. Being able to get wind into the animation is a smart idea, it would be even better to see a vector delayed movement, ie rather than seeing all the grass move at the same time, there's a distance delay to when the object moves, eg the grass on the right moves before the wind gets to the grass on the left, like you would see with a real gust of wind.
The traffic plugin also looks usefull too.
