About this Mod

!
This mod adds various new structures to Minecraft's overworld. The final goal is to add more structures that perfectly fit Minecraft worlds. This mod adds multiple buildings that suit the ambience and aesthetics of that biome. This pack will add around 30 unique structures to the game by completion.
There will be no backporting beyond 1.19 for the mod version and 1.18.2 for the datapack version.

FAQs

These are just some of the most asked questions I've had from people, but if you have any more, please leave a comment below and I'll try to help you as best I can.

1. Is it safe to update Immersive structures to a newer version?
Yes. If any serious problems arise because of that, let me know.

2. Is it safe to add Immersive structures to an already existing world?
Yep. Just note that the new structures will only spawn in newly generated chunks.

3. Is this mod for Forge or Fabric/Quilt?
All of them. I have a universal version for three mod loaders.

4. How can I locate the new structures?
For 1.18.2: /locate imst:[structure_from_list]
For 1.19+: /locate structure imst:[structure_from_list]

5. Does Immersive structures modify existing vanilla structures?
No

6. How can I report bugs/issues/suggestions?
Please go to my GitHub repo and make an issue there. A discord message will do.

7. Can I include Immersive structures in my modpack?
Sure, but make sure to give credit and a link to our page.

8. Can I have Immersive structures for 1.x.x, please?
Suppose it's lower than 1.19, no. Don't ask this question ever again. The technical limit is too high here.

10. Can I give Choicetheorem any kind of commission or support?
I can't take any commissions or monetary support due to a lack of time and mean to receive payments.

11. Can I use it on Aternos or any 3rd party downloads?
Yes, but you can download it via Modrinth, not Curseforge.

12. Is this server-side or client-side mod?
Immersive Structures is a server-side mod.

Frequently Asked Questions

Immersive structures server crashes on startup – what to do?

Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Immersive structures compatible with datapack and fabric and forge and neoforge and quilt?

Immersive structures officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.11, 1.21.10, 1.21.9. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Immersive structures – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Immersive structures consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
