But I wouldn't mind helping the rest of you guys out...
If you have an idea, or a feature you need... post it here.. I'll do what I can for ya, it'll be first come, first serve... minus those features that are obviously pointless, or ones I'm allready working on, and those that are waaay too time consuming... the really big, unique to a single map, time consuming features are fun to do and all.... but right now, I'm gonna put priority on realistic stuff, generalized buildings, rocks, trees, plants, spikes, crystal formations, alien stuff, boulders, stuff like that... Feel free to post a request for some super duper fancy smanchy building thing thats only gonna work on the center of your unique map... maybe I'll work on it, at least model it or something... but understand I'm gonna make the majority of mappers happy before the minority...

but PLEASE, post why you need the feature, and some drawings, pictures, sizes you need, something to explain what it is you want...
don't just say, "I WANT MARS ROCKS!"... I'll just ignore you....
if you say something along the lines of:
"I would like some clusters of maroon and orange colored geometrically irregular rocks of irregular shape, sized from 5ft in diameter, to 50ft in diameter... with cracks across them, and 1 or 2 large ones standing up, that look kinda like this:

or "Can I get some alien type trees and vegitation that would look simillar to

If you can't find a picture of something simillar to what you want on the internet, DRAW ONE IN PAINT!... lol it dosen't have to be fancy.. but images are alot better to work with than simple words... also, you can edit pictures you find and I'll go from there...
I'm probably over exaggerating on the detail per post on the rocks etc. but I'm doing so to make a point.
If you have something very specific in mind, provide as much information as possible, otherwise, don't plan on it coming out right... I can only guess so well...
