Frequently Asked Questions

How do I get a normal sword?

Kill a demon, get Ubuyashiki's invitation, right click it to find a toril gate
go into the gate and enter final selection (gear up first because it's quite difficult)
go back to the twins after 7 nights, choose your ore
bring the ore to a swordsmith, and the swordsmith gives you a sword

Where did the the custom swords go?

The new swords (like ice and frost) are now in KnY Extra Additions
- curseforge.com/minecraft/mc-mods/kny-extra-additions
- https://modrinth.com/mod/kny-extra-additions
- https://github.com/YeeticusFinch/KnY-Extra-Additions/

My world creation is stuck at 100%

UPDATE: Mt Fujikasane and Swordsmith Village region files now come from this mod:
- https://www.curseforge.com/minecraft/mc-mods/kny-worlds
This means that Mt Fujikasana isn't importing properly
Try upgrading to the latest version of Kimetsunoyaiba Tweaks
Otherwise, you can fix it manually:
- Go to your .minecraft folder --> kimetsunoyaibamultiplayer --> mt_fujikasane_cache
- If this folder is empty, then you've got a problem
- https://github.com/YeeticusFinch/KimetsunoyaibaTweaks/tree/main/region
- ^^ Download all the region files from this GitHub link
- Place all those .mca files into minecraft/kimetsunoyaibamultiplayer/mt_fujikasane_cache/
- Reload the mod and try again

The game crashes on mod loading

Make sure you have forge 47.4.0
Make sure you have the forge versions for 1.20.1 for all the following dependency mods
- Kimetsunoyaiba
- Mob Player Animator
- Player Animator
- GeckoLib
Make sure you don't have Optifine, it's completely incompatible

My spawns are messed up, there are no Hashira or Kizuki demons or named characters spawning?

Go into the config for Kimetsunoyaiba Tweaks (aka Kimetsunoyaiba Multiplayer)
Disable enhanced spawning
Enhanced Spawning will prevent named characters, hashira, and kizuki demons from spawning outside of raids and quests and special biomes/structures

How do I configure this mod?

I recommend using a config mod, like Configured or Forge Config Menus
Alternatively, you can go into your minecraft folder --> config --> Kimetsunoyaiba Multiplayer
- You can edit the .toml files directly

Missing textures

Yes sorry I haven't finished making all the assets yet
