Spawn Limit Override

When enabled, each entry caps the creature's share of the total spawn pool. Useful to prevent one boosted creature from crowding out everything else.

0.10

0.1 = 10% of spawns, 1.0 = uncapped (100%). Default per-dino is 0.1.

Config Key Reference

Key Mode Description
DinoNameTag Easy Internal tag name (e.g. "Rex") that ARK uses to match creatures. Case-sensitive.
SpawnWeightMultiplier Easy Multiplies the creature's default spawn weight. 1.0 = unchanged, 0.0 = no spawns, 2.0 = double.
OverrideSpawnLimitPercentage Easy Must be True to use SpawnLimitPercentage. Caps the creature's share of the spawn pool.
SpawnLimitPercentage Easy 0.0–1.0. Max fraction of total spawns this creature can occupy (0.1 = 10%). Requires OverrideSpawnLimitPercentage=True.
ConfigAddNPCSpawnEntriesContainer Advanced Adds new dino entries into an existing container. Does NOT replace existing entries — use ConfigOverride to replace.
ConfigOverrideNPCSpawnEntriesContainer Advanced Replaces all entries in a container entirely. Use this when you need full control, not ConfigAdd.
AnEntryName Advanced Arbitrary label used in server logs. Has no gameplay effect — helps you identify entries.
EntryWeight Advanced Relative weight of this entry within the container. Higher = spawns more often relative to other entries.
NPCsToSpawnPercentageChance Advanced Per-slot chance (0.0–1.0) that each NPC in the entry actually spawns when this entry fires.
MaxPercentageOfDesiredNumToAllow Advanced Caps how many of the container's total desired spawns this entry may fill. 1.0 = uncapped.
