Youll never know if u can model until u try and do it and let me catch this one in the bud. In the beggining it may seem hard and u might wanna quit but thats the way i see so many peeps give up. it was like that for me but i kept telling myself "i wanna see my crap in the game" a bunch of times and i finally forced myself to use lotsa tuts and just praticed. also try editing first it helps get u aquainted with the 3d enviro
Hey, what have you got to lose? I started modelling and I sucked.. but as DaKD said, keep practicing and eventually you'll find.. just as you are about to give in.. something clicks and you can model.. that's the way I found it, I mean, i'm still bad but i'm getting better every minute.. give it a shot!
