Was exploring comfortable levels of rooftop detail and possibly a night-time version when, suddenly, Blend Mode took things from Faber Castell to felt-tip.

Big reveal: It's the default setting.

One or two pips up from a straight line with the Up/Down buttons does the trick. Better width control with tighter node intervals, granted.

Timewise it is probably more draining than actual hand-drawn, but I am getting way better mileage out of it than I ever could from pen and paper. Best part is if November is coming up too fast, I can always revert to a low-details thing.?

Closed fractal polygons. Width variation comes from bounding back to the first node from the last with fractals dialled up slightly on the way back.

So I picked area 19 of the October community challenge. And this is the current progress of my getting in way over my head. I figured it would make an excellent opportunity to further the Castellfollit approach on the encounter map format (and will probably live to regret it).

Thank you, @Loopysue! I think it goes to show just how much the platform can help with realising one's ideas: the consistency of quality is what CC3 is all about, for me at least. I could never hope to achieve similar results on a free-hand platform in a million years. Give or take.
