The pre generation tasks are executed one after the other.
The pre generations is continued after restarts.
Chunks already generated are skipped on pre-generation.
If you run parallel pre generation, you should set "max-tick-time" in the ""-file to -1 to prevent crashes, because the tick time gets to long.
If you run parallel pre generation and get exception spams in the server log, you should restart the pre generation with a lower parallelization.

Server Config

The config file can be found in the "serverconfig" folder in the "world" folder and is named "world_pre_generator-server.toml".

Progression State

The progress state computed is in chunks.
You get the following information in the generation messages: "A B/C (D%) E chunks/s"
- Dimension (A)
- Chunk generated (B)
- Total chunks to generate (C)
- Percentage of chunks for which generation is finished (D)
- Rate of Chunks per second generated between this and the last message (E)

The mod is only available for version 1.14.4 and subsequent versions and is not expected to be back ported.
