should have been !== undefined (or a default argument in the function header rather), because roughness 0 is replaced with 5.

Why is that painter definition in the map file and not near the other painter?
Why does it copy 160 lines instead of adding one more argument to the painter and modify two lines of the paint function?

The effect of that +1 randomness is completely unnoticeable.

Is it a trick question? Aquarius?

Having this copy of the function helps with not losing it accidentally.

"hacky reasons" being the SmoothElevationPainter not producing the desired result.
A small blend radius leaves a steep impassable shoreline.
A large blend radius leaves too much sand.

targetHeight is the only difference in the code of the two copies of the function.

On Corsica & Sardinia, the passage just goes from start to end,
on Pyrenean Sierra it creates a passage from start to the center, then a passage from the center to the end,
which is why centerElevation is passed in this variant of the function but not in the other.

Fixed in rP20354.

Nuked in rP20354.

1 if statement-> direction.reverse();

2 if-statements -> Math.sign(x || 1);

always -PI/12

Code redundancy in case of failing hardware :p
