Known issues and information

  • If you are on 1.16.5 running an Intel GPU, this mod may crash your game if you try to turn on MTR fonts via MTR Mod. This is due to us using TTF font provided by Minecraft (For simplicity reasons), which will crash game before 1.17. (This doesn't occur after 1.17, you may safely turn on MTR Fonts)
  • Optifine with shaders may cause rendering issues (Such as text turned to red and characters turning to rectangle). In this case please uninstall Optifine and use the alternatives (There's nothing we can do about it at the moment)
  • Make sure you have downloaded the correct Minecraft version
  • Make sure the version you downloaded is compatible with the MTR version you have. (See Changelogs).
