As one of the devs of a structure mod, ALL Minecraft structures have godawful world placement. There really aren’t many tools to improve how they spawn other than to ignore the world entirely lol.
Funny thing to think about, when was the last time Mojang added a structure that cares about the world around it? Trial Chambers spawn underground, Trail Ruins spawn underground, Ancient Cities spawn underground, etc
No, don’t you understand? It is not for image editing
