Frequently asked questions
How do I know if Tectonic is actually working in my world?
Generate a fresh world and look for mountains that stretch for thousands of blocks and reach well above y=200, or scan a coastline for steep cliffs with overhangs. If your terrain looks like vanilla, the datapack/mod isn't loaded or wasn't applied to that world.
Why does my old world look unchanged after adding Tectonic?
Worldgen changes only apply to chunks that haven't been generated yet, so already-explored areas keep their old terrain. You need to travel into ungenerated chunks or start a new world to see the new biomes and terrain.
Can I use Tectonic with other worldgen or biome mods?
Tectonic is designed to work alongside many other datapacks and worldgen mods, but overlapping terrain or biome overhauls can conflict and cause odd generation. Check the pack's compatibility notes and test on a fresh world before committing to a long-term save.
Does Tectonic work on a server, and do all players need it?
It can run on a server, and clients generally need the same worldgen setup to see terrain correctly. If it's installed as a datapack on the server, vanilla clients can usually connect, but mismatches can cause visual or chunk errors.
