can't see the model witch's imported from .x

hi~~.
i am doing a FPS demo. I use the fps creator's gun model for test. I imported it, and seem no probelm in med. but when I use it on my demo. I can't see it.
what's wrong with that???
thanks in advance...

maybe you have an alpha channel on the texture

oh...so how I can solve it? and thanks
but i see it in med is ok
i use the WW2-> mas36->hud.x

go to object->manage skins->skin settings->Texture format and change it to 24bits

THANKS!!

you're welcome
