Cracks nether seeds from bedrock. This works in versions 1.18 and above since bedrock became seed dependent in that release. The overworld uses a different RNG, so the calculations used here are not applicable.
To use the Nether Bedrock Cracker, follow these steps:
After gathering the required data, you have two options:
You can use this tool to filter a seed list via bedrock positions. Simply load the list via the "Load seed list" button. Seed lists are text files where each seed is on a new line. Click here to view the format
PaperMC had a bug in their code that caused slight differences in bedrock generation. If you encounter a situation where your bedrock is shaped in pillars, similar to the bug report, switch the crack mode in the GUI from "Normal" to "Paper < 1.19.2-213."
If your nether was generated in a version older than 1.18, you can use the fungus cracker of SeedcrackerX to crack the seeds.
If the world-seed-search mode finishes with a false or no seed at all and the structure-seed-search mode found a structure seed then it's most likely that the servers world seed wasn't generated by the game but manually specified by the admin. Check this website to figure out how.
If you prefer to build the application from source instead of downloading it from the releases page, follow these steps:
You will need to install Microsoft Visual C++. MSVC is bundled with Visual Studio, but if you prefer a standalone installation, you can download it from: https://visualstudio.microsoft.com/visual-cpp-build-tools/
cargo build --release
