I'm trying to model my house using Blender. I'm stuck with trying to get a realistic tiled roof. When I follow a tutorial online, I think I'm doing all the correct steps in the Shading area, but it still looks flat in the the Cycles render.
This is the texture I'm trying to use https://texturehaven.com/tex/?t=roof_09 (although I will need to find a better one for my final design!).
But it looks totally flat:
What might I be doing wrong?
Here is my .blend file: http://files.staging.x-rm.com/nick/house5b.zip
