This version creates the pattern shingle differently, adds a ‘gap’ slider and second ‘Angle’ but it doesn’t help. The roof shape just isn’t appropriate at all for shedding water.
The yellow group is a half-hearted effort to use contour lines instead but it’s not even close to what is needed for a roof like this (which will never shed water anyway).
Learn from failure?
