Models are not coming properly

Hi,

I have a problem with imported models.

I have exported some models as double sided from max.

When i am importing them in to unity they are coming as single sided…

Can any one tell me what might be the problem???

Unity doesn’t do double-sided polygons. You can use one of the built-in shaders if you just need the visuals, but if you need collision you’ll need to model both sides of your object.
