Frequently asked questions

How do I actually start using this mod?
Install the mod, launch Minecraft, and create a new world—you'll see Terrain Diffusion listed as a world type option. After selecting it, click Customize to adjust your World Scale setting, then generate the world normally.
What does World Scale actually do?
World Scale lets you set how many real-world meters each Minecraft block represents, so you can compress terrain into a smaller space or stretch it across a massive landscape. A smaller scale means taller mountains and deeper valleys in the same block distance.
Do I need a good GPU to use this mod?
A dedicated GPU (NVIDIA or AMD) makes terrain generation much faster, but there's a CPU-only version if you don't have one—it will just take longer to process. Check your GPU in Task Manager (Ctrl + Shift + Esc → Performance tab) to pick the right version.
How do I scout my world before building?
Once in your world, run the command /td-explore to open the web-based map explorer in your browser. You can view elevation, temperature, and terrain layout to plan where you want to build before you start.
