NoTextureRotations

A Fabric mod to prevent coordinate exploits based on texture rotation and position offsets. Or if you prefer how it looks! Compatible with Vanilla MC, Sodium, and custom texture/resource packs # How the mod works This mod can either: 1. Disable block texture rotations and offsets 2. Replace the random function with a secure implementation, which will retain the normal visual feel of the game ## Configuration There are two ways to configure the mod in-game: 1. Install [YetAnotherConfigLib](https://modrinth.com/mod/yacl) and [ModMenu](https://modrinth.com/mod/modmenu) 2. Install [Sodium](https://modrinth.com/mod/sodium). A page for NoTextureRotation settings will be added to the Video Settings. The configuration file is located at: `.minecraft/config/no-texture-rotations.json` ## What's the exploit? Many blocks like grass, dirt, and stone have *variations* that rotate or change their textures slightly. Texture variants are not inherently bad, they make the game visually more interesting as they prevent blocks from looking "same-y" when many are next to each other.  The problem is that the "random" number used to select the variant is seeded by the block's position in-game. No world seed is required. Offsets works similarly, some blocks like flowers offset their position from the center of the block with a "random" offset. Any screenshots or videos that show examples of these blocks are susceptible to an attacker cracking the block coordinates. On anarchy servers, this can be particularly powerful - leading to bases with images or videos shared being found. This is not a new discovery, and the method has been known since at least before 2018 and is still regularly used today in reversing panorma seeds.
