FOSS gamedev and creative worlds

I found this bug on latest git minetest and minetest_game. It happens on mapgen v6 snow biome, always on same 'y' altitude.



I used the below perlin noise attributes and mapgen parameters (seed and map coordenates on the attached image):

there's another mapgen v6 bug, but in the source code
l often saw that dirt with grass, and even trees are generated at places they shouldn't, e.g.




Edit: l already wondered why the snow on your screenshots has the same height everywhere…

@Hybrid Dog, the latest git has its own snow biome, rather than adding splizards snow mod.

l know, l think that Splizard's biome looks better, but l need to test it, thanks for remembering me.

May be this image zoom makes the bug more clear.



Stone generated up to y = 45, then the mapgen places snow over it, and then continues generating stone at y > 45 making this linear gap. I think it's a bug.

@Hybrid Dog, didn't understand your post sorry.

The bug is at y=47 which is a mapchunk border. Mgv6 is very buggy at y=47 if made higher with custom noise parameters, the bugs are hard to fix, the gap is really ugly though i might try to fix it.
