Save system has been implemented!
Starting from 1.0.3.1 and onwards, updating to a new version will keep your progress intact!

‼️If you want to retain your save file during transition to modpack (or in general) follow these steps‼️

  • Go to your modpack instance and press the kebab button (three dots)
  • Open modpack folder, and go to saves/Atmos
  • Copy data and advancements folders to somewhere else (throw it onto the Desktop or something)
  • Install a new patch, launch the map and quit to the main menu.
  • Replace the data and advancements in saves/Atmos of your Modpack to the ones you saved locally.
  • Enjoy! This also works for when you want to transition to using Modrinth. Just copying those 2 folders will retain your save data and you can use it in any other version!

On Install: Some in-game settings must be changed for the best experience. This pack comes with FancyMenu preinstalled, so clicking "Auto-Settings" would set the game up for you. ANY type of custom shaders is NOT RECOMMENDED, as they conflict with the vanilla core shaders, used to render a huge portion of the map and a lot of different mechanics. If something breaks because you enabled a custom shader - it's entirely on you.
