About
Open Terrain Generator is a configurable world-generation engine for Forge and Spigot that lets players create or use presets to shape Minecraft worlds, without requiring Java knowledge to make a preset. Its settings cover terrain height and noise, biome types and placement, climate, rivers, oceans, caves and canyons, as well as the blocks, ores, plants and other resources placed during generation. Presets can add custom objects and large structures, including trees, rocks, dungeons and villages, with rules for where they appear; they can also configure mob spawning, custom mobs and loot, and options for vanilla structures such as mineshafts and strongholds. World creators can customize foliage, water and sky colors, generate biome maps from images, and create additional dimensions, including alongside a vanilla overworld. The in-game world-creation interface lets users select a preset, adjust world settings and add, edit or remove dimensions; the engine also supports configuration files for sharing and reusing biome settings. OTG is an engine rather than a complete content pack: it includes a default preset close to vanilla generation, while named options such as Skylands, Vanilla Vistas, Flatlands, Void and Biome Bundle provide different ready-made worlds.

No harmful code found
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.10.2 to 1.16.5.
We checked its files and read their code, without running it.
What it can do on your computer
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Found in the mod's own code and in code libraries built into it. See Privacy
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Forge 1.12.2 to 1.16.5.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for Forge 1.12.2; 1.10.2 to 1.11.2.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.4 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Uses folders outside the gameFinds the Minecraft folder.
- Looked for, not foundWe looked for these in the file and did not find them.Other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends about you
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.10.2 to 1.16.5.
We read its code without running it: it contacts 1 web address while you play.
Like any connection, each address it contacts sees your IP address.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 4 files, for Minecraft 1.10.2 to 1.16.5. See each file in Releases
- report.mcstats.orgPurpose not known.Unencrypted (http)Plain http: what is sent to this address is not encrypted on the way.
AI
No sign that AI was used to make it
We looked for AI tools in its texts, files, images and code history and found none.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Not on Modrinth.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Nothing found
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found4 of 30 changelogs read

- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found21 images read
