I am trying to do something as simple as exporting a prefab (the sliding door), from the AngryBots project to a new project so that I can use it in a new project.

I have exported the prebab to a package and tried imported on the new project. However, after importing it, I don't have the textures and materials associated with the prefab. When I drag the prefab into the scene I get the model all in pink (because there's no texture associated, I guess) and have to associate the textures and materials again manually.

Isn't there a way to have the textures and materials already associated?

I am exporting with the dependencies.
