Texture scale

Texture scale

Hi there,
I have a problem with one of the textures. In 3d Max the texture scale looks nice, but when I import the scene to the engine, it scale the map to be very small.
I tried to unwrap the part of the building and change the size of the texture, but it didn't help to solve the issue.
What could be wrong?
Please see attached images,

Thanks.
