As my title states, i would like if we were able to specify which dimension Ancient Shrines can spawn in, maybe with an option in config? Currently we are hosting a server that runs a modpack containing Astral Sorcery, and because we are using a multiworld plugin, our spawn is the "main world" and the worlds people are allowed to settle in are different dimensions. No Ancient Shrines are spawning anywhere, because spawn is a void world that only contains our spawn structure. This has made it completely impossible for our players to even start your mod. I sincerely hope you are willing to consider this, as your mod is a big part of the pack and a lot of people would be saddened by not being able to play it properly.

You can in 1.8.9 add dimension-id restrictions to structures

You can use the "/astralsorcery help" command to see how to spawn one via command, but the shrines are biome gated not world gated. They spawn in other dimensions by default.

Oh boy, i can't believe i didn't think to check commands. I feel quite silly now.

I've explored singleplayer worlds and had no difficulty finding them, but we've been in closed beta to around 30 people for almost a week now and no one has found a single one in either of our worlds, despite several of us actively looking for them. I'll let you know if one is found this weekend, as we should have more online and I can have people head out in different directions all at once, but for now it's looking like they aren't spawning at all.

What is being used to generate those worlds? Are you checking cold/mountain biomes? Is there enough flat space to meet the config file limitations for spawning them?

That is our world management plugin ^

And yes, we have been exclusively looking in mountain biomes. Other modded structures and biomes have spawned fine.

May want to check with them for how they are handling structure stuff, then, since unknown how they're changing things.
