Limitations & compatibility
- Noise samples are not a complete playable-map generator: mesh/tiles, walkability, placement, collision, persistence and gameplay are project work.
- Godot has native FastNoiseLite; do not install a duplicate library solely to get that existing capability.
- Some Godot cellular modes can exceed the usual noise range; map or clamp values based on the selected algorithm and project needs.
- No cross-language identical-output, platform compatibility, speedup or native/import/export test is certified here.
- Promotional examples and web-preview dependencies are outside this code-only review; no media is approved for rehosting.
