Transforms world generation into deterministic block layers by Y-level, with configurable block blacklists and forced-layer overrides.
⬇ Download on ModrinthRandom Layers
Random Layers transforms world generation into clean, deterministic strata: each Y-level is assigned a single block type across the world. The block for each height is chosen from a valid pool using your world seed and dimension, so results are chaotic but fully repeatable.
Features
- Deterministic generation per world seed + dimension
- Replaces terrain and generated structure blocks by Y-level
- Supports vanilla + modded blocks in the layer pool
- Configurable blacklist support:
- Namespace blacklist (example: create)
- Exact block ID blacklist (example: minecraft:tnt)
- Compatibility/safety toggles for structure handling:
- Preserve all block entities
- Skip replacing block-entity blocks
- Preserve vanilla critical blocks
