Pixie - I'm not understanding something here - relating to something someone else said about roof shading on an entirely different thread just yesterday.

I'm a bit confused about why you split the shading diagonally across the rooftop. I'm my mind's eye a flat plane that is neither kinked nor curved, and which faces one direction only, would be shaded all the same... or would it? It's something I've never even thought about before because roof shading is automatic in CC3, but now that I've read that other thread I'm a bit confused about it all.
