The ground that stayed painted
written 2026-10-01The plan was to generate the floor of the board the way everything else on it is generated. A measurement from the road chapter stopped it, the marsh nobody could see got planted instead, and the generator spent the whole job trying to hand the floor back.
Every castle, tree, rock and animal on this board was generated by a machine that turns a written description into a 3D model. The obvious next step was the ground itself: cut the board into tiles and generate each kind — grass, hills, bog — as a model of its own.
That step was never taken. This chapter is about why not, and about what was built instead.
Anything set like 0.0665 was measured by a machine and generated into this page from the committed results. Everything else was written by a person.
The cheapest thing on the board
The ground on this board is drawn by the game itself, not loaded from a file: a single sheet of land, bent into hills and dips, coloured by what each tile is. It costs about 33 triangles a tile. Nothing else on screen is that cheap.
The generator has a floor of its own. The smallest model it will make is 500 triangles. So a generated tile would cost 15 times what the ground it replaced costs — for every tile, across the whole board — before it showed anything new at all.
Four pixels, again
The cost alone might have been worth paying, if the result could be seen. The road chapter had already answered that. On a phone, a road on this board is about four pixels across, and the texture work aimed at it was answering a question nobody could see the answer to.
A ground texture is drawn at exactly that scale. Every pebble, every tuft, every crack in the mud of a generated floor tile would land in the same handful of pixels and come out as a colour.
And there is a mismatch in the tool itself. The generator makes objects: a thing you could pick up and turn over. A floor is not a thing. It is the surface everything else stands on, it has to meet its neighbour on every edge without a seam, and it is never seen from anywhere but above.
So the owner ruled: the ground stays painted. What goes on the ground is generated — rocks, bushes, reeds, the clutter of a real landscape — and the painted floor underneath stays exactly as cheap as it was.
A tenth of the tundra had nothing on it
That ruling made one gap impossible to ignore. Marsh is a real kind of ground in this game: slow to cross, with its own rules in a fight. On a green board it is 4% of the land. On a tundra board it is 12%.
And on the board it was nothing. A bog drew as a slightly darker, slightly lower patch of grass with not one thing growing in it. Every other kind of ground had something standing on it; marsh had a colour.
So marsh got a set of its own: reed clumps, cattails, sedge tussocks, standing pools, drowned snags, rotting logs, mud hummocks and moss-capped stones, scattered up to two to a tile so no bog repeats. Across 5 full-size tundra boards that is 3,022 pieces, on ground that had none.
The first bog plant was a health check
The first piece of the marsh set was not made for the marsh set. Weeks earlier, somebody needed to know whether the generator was alive at all, and the quickest way to find out was to ask it for something. They asked for a clump of reeds.
It came back looking like a clump of reeds, and the owner asked to keep it. So it is on the board — but it was made before anybody had decided how heavy a marsh plant should be, and it shows. It is 6,927 triangles, 14 times the floor every other piece in the set was made at, and it stands on the little patch of mud its one-line request asked for — the very thing every later piece was told to leave off.
It is still the rarest piece in the mix. Keeping something because the owner likes it and keeping it because it is the best of the lot are different decisions, and the scatter weighting is where the difference is written down.
The floor kept coming back
The ruling was that the generator would never make floor. It did not get the message.
These two batches cost 47 casts, and 14 of them were sent back. 8 of those were sent back for the same reason: the generator had built a piece of ground, or the grey backdrop of its own reference picture, into the model. Moss-covered stones arrived sitting in a curled grey tray. A drowned tree arrived welded to a flat wall many times its size. A bush arrived on a grey disc that would have read, on green grass, as a ring of ash.
None of that tripped a gate. Every one of those models was a single object, with one material, within its size limits. They were caught the only way this project has ever caught a shape that is wrong in a way no number describes: somebody opened the picture and looked at it.
