Here are some final tweaks made to this project before finally putting it to bed. On doing a conversion of the set to another format, I noted that the floors were much improved during the conversion process when compared to their native 3DS Max incarnation, and so that gave me the impetus to revisit this aspect of the asset to see if I could get results more in line with the new converted version, and I think the results are a great improvement on what came before. Right that's it. Leaving this thing alone now.
