This section will only cover config options whose effects are not obvious.

decorationHacks: Disabling this will prevent structure replacement features like the tree, village, etc from working.

inventoryGeneratorGenerationMatcher: Uses expressions and loot table names to determine whether they should generate. LoadMatcher prevents them from laoding. See Expressions page.

mazeTimeout: Sets the max time a maze generator script can run for. Useful for servers. If your mazes are frequently timing out, you should re-evaluate their generation rules and room placement. You may be making their valid generation paths too strict.

structureGenerationMatcher: Used to disable certain structures from generating. LoadMatcher prevents them from loading. See Using RC As A Utility.

structureSpawnChance: Universal spawn chance matcher for all structures (controls avg structure frequency). 0.5 means half as often as the default. I find 0.75 to be a good value when you have lots of large structures as 1.0 is too dense. Not recommended to go above 2.0 due to cascading generation lag.

universalBiomeMatcher & DimensionMatcher: Takes an expression for blacklisting/whitelisting to save time doing it across every structure. See Expressions.
