hey. i'm back once again with a modeling problem. I'm not sure where to post this for help but you hopefully you guys can figure out what I can't =o so I recently made a grease gun for a mod and the model before I export it looks great. however when I export it then import back... it's flipped inside out. yes. inside out. you it's hard to explain. here's a picture:greasy.jpg
the bottom one is the model before export.
I don't understand what's going on. i've made other models and never have had this happen.

. i'll google it but I assume that I won't get much. i'll post a gmax file with the non exported model and the exported and screwed up one if anyone requests it.
