Seems the atlas is rendering the world based on the seed number ignoring everything that other mods do change about world generation.
As sweet as the map looks like, that makes it totally useless unless you play vanilla with only atlas as mod.

Sky mods: Void dimension rendered as if it would be a vanilla world
Dimensions from mods (twilight forest, galacticraft etc.): Empty map
Mods that add/remove structures: Completely ignored by the map. You end up with villages / structures on the map that are not there and others missing.
Disable structures in world: Structures still appear on map

Mod compatibility can be achieved using resource packs since 6.0.0. So this generic issue is obsolete.

this is accurate, tested with Lost Cities mod on every variation of the city render settings and OTG Biomes bundle.

i'll give you the same offer i made the mod creator of animania, i have access to a data server rack and a team of testers which includes me among them, i'd like to use this mod in a new hardcore modpack im creating and so im willing to give you any and all support you need to fix this mod up proper. just give me a msg at my discord https://discord.gg/5FPK6v9

Are Lost Cities considered biomes? If not, they'll need their own IStructureWatcher. Shouldn't be too hard to add. If they're biomes, #161 should help with it.

They are definitely not biomes, and I don't think they're anything like vanilla structures. Lost Cities has its own API though.

@Kenkron for what it's worth, i have a fairly hacky Lost Cities compatibility mod here.

I didn't attempt to do it as a modification to antique atlas (and thus position for a pull request) because I have a great deal of trouble reasoning about java, and complex codebases are very difficult for me.

That said, it seems like this sort of thing seems like a good use of the API (barring the limitations I mention in #195 ), so unless you think it needs to be in Antique Atlas itself, I'll continue working on this (while lightly nudging McJty to improve his Lost Cities API as well, which is currently incomplete for these purposes).

for sky island world, like sevtech sky island version modpack, it would be better to making a obvious boundary between void biome and normal biome.
