I'm guessing you're referring to the building on the left of both shots. It's important to know that materials don't carry over from Blender and need to be setup separately in Unity.

Could you show us the Material you have applied to the object?

I could be wrong, but I wonder if this could be a compression issue instead? You might have to change the compression settings.

 

Looks like an alpha issue to me.

For anyone arriving here now with a similar problem, try to make your shader opaque/non-transparent or set the alpha value ( float4(r,g,b,1) < last value of float4 ) to 1.

It looks like the color map( /diffuse ) is plugged into the alpha, making black values transparent, white ones opaque, and interpolate in-between.
