Factions ReForged

/f map item terrain — claims over real ground

The existing atlas answers who owns this region. This one answers where exactly is that line relative to the river — rivers, forest and coastline drawn underneath the claim colours.

It is close in — 256 blocks — and that is a constraint rather than a taste. Claims come from the faction store and are known whether or not the world is loaded, which is precisely why the atlas can be complete at one chunk per pixel. Terrain is not: drawing it at that size would mean generating 16,384 chunks, which is a server stall, a great deal of disk, and a free map of country nobody has walked. So the survey reads only chunks already in memory and falls back to flat claim colour where the world is not loaded. Walk somewhere and take another.

There is no transparency in a Minecraft map — a pixel is an index into 64 colours by four brightness levels, not an RGB value — so the wash is mixed in software and snapped to the nearest colour the palette can actually say. Relief shading is vanilla's own north-slope comparison, without which the ground reads as flat blobs; borders are drawn as more tint rather than more brightness, which would fight that shading.

/f map item is unchanged. Its completeness is the whole point of it, and the two cannot both be had.
