Hi, try this : In your 3d app, link at least one texture map to your UV layout on each object you export.
Make sure that these textures are already in your unity project folder. Thats it! 
Cheers
Your imported models should have autogenerated materials.
Just put your texture in (every) material.
this is the way i do and have refuse from asset store, for have no linked textures. i saw another models from asset store and they have material included in the fbx imported, how can i do that?
thanks.
well, i fix that, the mistake was i put in the fbx importer to no generate materials. thanks for your help
