C2ME Fabric 0.4.0-alpha.0.27 (gRm1ZAvc, 2026-08-14) — no config file; async chunk I/O+gen.
Tuned for Tectonic 1.28 expansive (vertical_scale 1.28, continents_scale 0.19) + Noisium/FerriteCore/Lithium.
Compatible with ChunkSmith adaptive throttle: ChunkSmith throttles pregeneration (targetMspt 45, tickBudget 10, dispatch 100) while C2ME parallelizes runtime load — no conflict.
If MSPT >45 or TPS <19 during /chunksmith pregen or exploration, lower dispatchMaxConcurrent to 75 or throttleCeilingMillis to 25.
Updated 2026-08-27 from 0.3.0+alpha.0.364 → 0.4.0-alpha.0.27 (backport, +compat fixes). Test: terrain/biomes/structures/teleport/save/restart.
If C2ME causes worldgen errors, remove it (do not force) — report BLOCKED.
