Woodlight Standards is made specifically for Minecraft 1.16.1 / MCSR Ranked.

How it works

Vanilla Minecraft uses unpredictable random number generators for fire spread and lava ignition, meaning two players with the same seed and identical portal setups can get wildly different woodlight times, anywhere from instantly or over 2 minutes, purely based on luck.

Woodlighting Standards replaces this with a seeded system where the time to light a portal is derived from the world seed, an attempt counter, and the quality of the player's setup. Given the same seed, the same portal will light at the same time, every time. Better setups (more burn slots filled, more lava in range) result in faster lights.

Currently Solved RNG:

Seed-deterministic portal light time via cumulative probability
Vanilla per-tick probability math (not arbitrary scoring)
Exact vanilla lava walk pathing checks
Vanilla flammable block registry checks
Deterministic fire placement from lava (seed-derived timing)
Deterministic fire spread (lava → fire → fire → portal)
Deterministic block burn-away timing
Canonical position keys (same setup mirrored/rotated produces identical fire timing to reduce incosistancies with same setup but different sides of lava pools)
Persistence across save/load
Fire suppression in portal subchunks (prevents vanilla RNG interference)
Biome humidity not factored in
Difficulty for fire spread

Disclaimer: Changing difficulty mid-timer will change the time to light final time. The same seed on different difficulties will produce different woodlight times and same with different setups.
