Sky Archipelago: FTB Skies 2: Aero config options

Whether anchor islands use extra fragmentation features that create small outcroppings/debris.

If true, extra blending samples run only near river/beach boundaries.

Whether river/beach terrain profiles blend into neighboring non-river/beach profiles.

Whether the bowl/crater island archetype is allowed to spawn.

Whether the classic island archetype is allowed to spawn.

Whether satellite/spire companion islands generate around anchor islands.

Cluster spacing mode. CONSISTENT uses fixed spacing. DYNAMIC picks deterministic per-world spacing from min/max.

Whether the crescent island archetype is allowed to spawn.

Whether Sky Archipelago custom structure placement/support rules are enabled.

Whether island clusters should be skipped when sampled biome is ocean.

Case-insensitive path tokens used to infer MEDIUM_GROUND category when no explicit override is present.

Whether legacy hamlet-category structures may use their compatibility fallback placement path.

How island radius sizes are selected. RANDOM preserves global min/max behavior, SPECIFIC uses small/medium/large bands.

Source-fluid block used by the optional ocean layer. Use a registered block id, such as minecraft:water.

Whether to fill an optional ocean layer below the sky islands.

Whether to shape an ocean floor beneath the ocean surface using deterministic noise.

Whether vanilla shipwrecks may bypass their native biome restrictions and spawn anywhere.

Optional per-structure placement categories in the form modid:structure=CATEGORY. Preferred categories: DEFAULT, SKY, SMALL_GROUND, MEDIUM_GROUND, LARGE_GROUND, GROUND_VILLAGE, STRONGHOLD, UNDERGROUND, WATER. Legacy aliases still supported: SMALL_SKY, SURFACE_SKY, HAMLET_SKY.

Case-insensitive path tokens used to infer SKY category for floating structures when no explicit override is present.

Structures to skip entirely before placement validation. Leave empty by default so future special handling can still be added later.

Structures that bypass normal support/grounding validation and are committed with minimal checks. Whitelisted structures still require nearby-island presence via the whitelist void guard. Examples: modid:sky_temple, modid:airship_wreck, modid:floating_platform

Whether smaller sky structures may use their compatibility fallback placement path.

Case-insensitive path tokens used to infer STRONGHOLD category when no explicit override is present.

Whether larger sky-surface structures may use their compatibility fallback placement path.

Whether the terrace island archetype is allowed to spawn.

How overlapping island terrain columns are resolved.

Case-insensitive path tokens used to infer UNDERGROUND category when no explicit override is present.

Case-insensitive path tokens used to infer GROUND_VILLAGE category when no explicit override is present.

Category inference order when no explicit override is present: SKY, GROUND_VILLAGE, STRONGHOLD, UNDERGROUND, WATER, then MEDIUM_GROUND. Keep broad MEDIUM_GROUND tokens empty unless you need them; normal uncategorized structures still use fallback/default placement. Case-insensitive path tokens used to infer WATER category when no explicit override is present.

Enable adaptive TTL tuning for the worldgen column cache.

Emit periodic worldgen cache metrics (hit/miss/eviction age) for tuning cache unload behavior.

Serialize final structure placement mutations for compatibility with parallel worldgen mods such as C2ME. Disable only for benchmarking or debugging.

Experimental: retain only a verified native start-to-portal path when fitting strongholds on islands.

Place category-colored wool pillars and log coordinates for structure generation attempts.

Broadcast accepted POI coordinates in server chat for debugging.

Master toggle for Sky Archipelago structure debug output (verbose placement logs + debug broadcasts).

Guard per-structure feature placement failures so one bad structure cannot crash chunk generation.

Strict mode for structure placement crash shield. When true, guarded placement failures are rethrown.

Emit detailed accepted/rejected structure placement logs.

Suppress per-structure verbose logs for SMALL LAND placements; aggregate summary still records them.

When enabled, only emit verbose logs related to UNDERGROUND structure placement.

Emit periodic worldgen performance metrics. Intended for profiling; includes terrain and structure timings.
