Wooden fences between houses and roads, placed automatically across the village

I wanted to put up a boundary, something like a wall, between the houses and the roads. I drew where the fences should go in yellow on three village screenshots (in front of the shop, in front of a house on the south side of the east main road, and the corner of the smithy yard), and in all three spots the line turned an L-shaped corner along the front path. Instead of placing a few by hand, I decided to place them across the whole village by rule.

What I built

I used the pack's four types of wooden fence at 0.8× scale, the same as the other fences in the village. One section is about 1.95 m long and about 0.93 m tall. The section type isn't random; it's set by position. The NPC in front of the shop still stands in the yard inside the fence.

The line the fences follow is 3.7 m from the center of the main roads (the edge of the stone paving), 2.0 m on alleys and front paths, and 1.1 m from the plaza edge. Fences only go up where there's a house (including annexes) within 10 m outside the line.

They break on their own at paved entrances and intersections, and along a front path they turn the corner only up to 2.4 m in (1 section). They avoid house walls within 0.9 m, the plaza, the waterfront, retaining walls, props, trees, street lamps, NPC bodies, and anything within 1.6 m of a door or arrival point. If an unbroken stretch is 1.6 m or longer, as many sections as fit are placed centered in it. Three houses whose walls are only 0.5–0.7 m from the paving edge, with no yard, get skipped.

Fences can't be walked through, and after placing them I rebaked the pathfinding data (NavMesh). Paths connect from the south entrance to all 7 doors and arrival points, and all 8 NPCs have a path to within 2 m (12–16 of 16 directions). Actually walking around and talking to them is for next time.

Things I thought about

• Pulled the line in to the edge of the paving. At first I set the line at 4.95 m with at least 2 sections per stretch, and got only 62 sections; they sat too far from the road and were broken up here and there. Pulling the line in to the 3.7 m paving edge and loosening the overlap check gave 83, and allowing corner turns and 1-section stretches brought it to 94.
• Only avoid NPC bodies (96 sections in the end). At first I left 1.6 m clear in front of each NPC, and the fence in front of the shop almost disappeared. Talking range is 2 m and clicking walks you to 1.7 m in front of them, so as long as an NPC stands within 1.5 m behind the fence, you can easily talk to them from the road.
• Wooden fences, not stone walls. The pack had no fitting module for a low stone wall (its stone walls are building-wall sized).

Next up

• In a few places a single fence section stands alone. If it bugs me, raise the minimum section count or remove them spot by spot
• Running the full generation again may shift the trees and grass behind the fences a little
