Regarding ddanrwood81 review: it clearly stay in description (parameters of the model): checkmark at plugins used.
Let's be clear: This scene is using excellent 3dsMax FREE plugins only for floor. These are:
Multitexture
https://cg-source.com/MultiTexture
Floorgenerator
https://cg-source.com/FloorGenerator
Download them and install if you would have proper floor material. It's super easy.
