baking textures for unity

hi , my first post here . I want to import a lamborghini model from 3ds max to unity . when I was working in flash and it’s 3D libraries , I used to bake the textures of the model , and export the .DAE file to my project and everything was fine . but in unity things are not like that and when I bake my model and export .FBX and import it to unity , the glasses of the car seems to be black in unity . anyone has any ideas why is this so?

thanks

You probably aren’t using a ‘transparent’ type shader. Have a look through the different kinds of materials you can use, and pick one which has transparency!

I set the shader to different kinds of transparent but still doesn’t work . I’m trying to import this model to unity : http://www.gfx-3d-model.com/2011/02/lamborghini-lp670-3d-model/#more-1559
