To find a seed in versions 1.18.X or higher, you must collect specific bits of information from structures.
Configuration Requirements
Open the GUI using /seedcracker gui (for 1.19.3+) or /seed gui (for versions before 1.19.3). Ensure that Emeralds, End Gateways, Biomes, Desert Wells, and Warped Nylium are DISABLED, as they are not updated and may provide false data.
Bit Requirements
You need to collect 40 liftable structure bits and 32 regular bits from the following supported structures:
- Igloo: 9 regular and liftable bits
- Desert Pyramid: 9 regular and liftable bits
- Jungle Pyramid: 9 regular and liftable bits
- Witch Hut: 9 regular and liftable bits
- Shipwreck: 8 regular and liftable bits
- Pillager Outpost: 9 liftable bits
- Ocean Monument: 9 regular bits
Any combination works (e.g., 3 shipwrecks, 1 pyramid, and 1 igloo). You can track your progress with /seed data bits.
Process Flow
- Detection: A structure is considered found when an outline appears around it.
- Automatic Search: Once enough bits are collected, the search starts automatically (usually takes 1-5 minutes).
- Refinement: If you find duplicate structures, the mod may require additional structures to narrow down the seed. After narrowing, it uses dungeons or the hashed seed for a brute-force search.
Troubleshooting: Structure not outlined
If a structure is not outlined, ensure the outline feature is enabled. If it is enabled but still not working, it may be due to aggressive Anti-Xray plugins, corrupted structures (missing/extra blocks), or non-vanilla world generation. If the structure is intact, approach it closely and run /seedcracker finder reload to re-scan.
