Hi Guys
Thanks for the replies and advice, it is very much appreciated. I have actually looked into buying Hal Archviz toolkit, and although it looks like an awesome toolkit, I would rather try do this project myself. I really want to learn UE4 and set this up.
I have a question about my workflow. Once I have prepared my tile library in Substance Designer and exported to UE4, would I use Substance Plugin for UE4 to manipulate tiles and tiling pattern settings inside UE4? Would I therefore not need to use UE4 Blueprints to change tiling patterns etc, I would use the Substance Plugin for UE4?
I am also going to take a look at Bitmap2Material, see how far I get.
Thanks again for the feedback.
Kind regards
