The story
Built because one run was never enough
One country was too big for one generator
Arnis turns one map selection into one Minecraft world, one area at a time. A whole country in a single pass means days of compute and one giant, fragile write.
So Meld runs many
A grid of region-aligned cells, one arnis per cell, in parallel, all sharing one origin, one seed and one elevation lock, so every cell agrees on where the world is.
Then melds them into a single seamless world
Each finished cell’s region files merge into one master world. Seams fall on region boundaries, a drift guard refuses anything misaligned, and you walk it as one place.
Meld started with one goal: render all of Romania. Now it renders anywhere, as an app.
