I'm back in architecture with this really cool thing which will decorate you scene for sure!
If you are a game designer, an indie developper this will surely help to improve your scenes, I had test it on UE4 and as FBX is used for UNITY there should be no problem to use it over there.
As a game dev myself I can insure you all the support needed to help you use this piece of architecture.
You will find the diffuse and the normal texture.
