Frequently asked

How do I install Complete And Total Terrain Overhaul (CATTO)?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Complete And Total Terrain Overhaul (CATTO) safely?

Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.

Which Minecraft versions does Complete And Total Terrain Overhaul (CATTO) work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old mod with no declared version as untested on modern Minecraft.

Details from CurseForge, where the author last updated it on 23 Oct 2026. We do not host files or republish descriptions. Available download links point to the author’s own release.
