Problem with exporting 3D models from 3DS Max into Unity; wiremesh only in preview mode, no texture or color.

Hello.

As you can probably tell, I'm a beginner at Unity, 3DS, and their ilk. I'm trying to get the hang of these programs for a Digital Design class that I'm taking.

The model I'm trying to export from 3DS is a tank that my instructor let me upload from a CD that he has.

I can upload the wiremesh frame into Unity, but I can only view it in "Preview" mode; I can't even see the frame in "Game" mode.

I try and export the file from 3DS and it doesn't even show up in the file select. I dunno what to do anymore!

HELP!

Thanks.

 George
