Before You Add It to an Existing World
Noisium Forked speeds up noise calculations but should not alter the shape of terrain, caves, or biomes. Still, any mod that touches worldgen deserves caution in a world you care about. Back up your save before changing your mod list, and test in a copy first.
Safe Adoption Steps
1. Back up your world folder so you can restore it if anything looks wrong.
2. Add the mod to your pack and launch into a copy of the world.
3. Travel to areas you have not visited yet, since already-generated chunks are stored and will not change.
4. Compare new terrain against your expectations. Biomes, cave systems, and surface shapes should look consistent with the seed.
5. If terrain looks correct and loading feels smoother, apply the same setup to your real world.
6. If you later remove the mod, note that existing chunks stay as they are; only future generation is affected.
Pack-Building Tips
- Keep worldgen-affecting mods to a minimum so conflicts are easy to spot.
- Test each new worldgen mod in isolation before combining several.
- Recheck performance after major pack updates, since other mods may change how much noise work is needed.
Following these steps lets you benefit from faster generation while keeping your world intact.
