Texture not showing up in Preview

I'm using Aero to create an an outdoor augmented reality (AR) pop-up show featuring life-size renderings of brick-and-mortar stores from popular modern retail brands. We will be creating life-size renderings of the retailers' physical stores, allowing customers to explore the stores and see the products in person, even if the physical stores are located far from the pop-up show.

We are creating our models using magic voxels so that our triangle count is under 15k. When I upload the model in Aero it has all of its textures but when I send it to be viewed the textures are gone. 

How can I stop this from happening?
