Among the plants... What about a pregenerated flag to set,that specifies what -season- it is? That would allow Eon to keep the Solid Growth stuff encapsulated, and allow for more color variance. We definitely need more trees; birches, willows, redwood, cypress. Maple. Blue spruce. =lots= more conifers, possibly with a resolution slider, to allow for distant trees to be as low poly as possible (distant forests anyone?). Several of the ground covers would be very nice, like heath, ground ivy, and for the real sicko's, kudzu. Can't do a proper Appalachian render without the stuff there somewhere... :P Definitely hedges like boxwood. Snapdragon. Maybe some flowering bushes. Lichens and mosses would be a wonderful addition, as well. Those tend to get forgotten as they are so small, but the abscence of them is noticed almost all the time.
