DISCLAIMER!!! I am by no means a modeller, I am many other things, but not a modeller.
I thought it would be good if we had at least a few assets, so I have just quickly modelled this barnhouse thingy.
It is very low poly [1100] and I just quickly threw the textures together (I will put a little more effort into it once I import it to UE4)
But what do you think?
