Ok, I'll see what I can do for mappers. Just write me a long ass list of props you need. Incldung references will get the job done quicker I'll post my WIP here.
Rocks Large enough so people can hide behind them and vehicles have to drive around. Now the same ones get used again and again, in best case with a slightly altered texture. And it would be awesome if you could remake the trees from episode 2. I'm using them in a map atm, but apparantly copyrights on them causes certain restrictions. I'd love to have similar ones, with the same amount of tri's or whatever, and also good looking lod's (not like the orex trees, who go from whitish green to dark green). But most of all rocks, if possible with several skins: desert, moss, bare rock, other rock, ... As for none natural ... some other resource prop to show where a resource spot is. Something technical looking perhaps. And it should have a hole somewhere from where the smoke goes up (until a ref is placed) I'd like to know what you CAN model though. I'm used to hearing "nothing organic/natural" from modelers.
Make animated models of dancing badgers, mushrooms and snakes so admins can drop them when they get bored.
