About this Mod

Stop Unloading My Resourcepacks

Prevents the game from disabling all resourcepacks if a shader-related error occurs. Instead, errors will be displayed in-game, can be configured to show errors in chat, a box in the top left, or both

This mod also adds a few QOL features for developing shaders, read more below

Things this mod prevents from disabling resourcepacks

The following things in vanilla will forcibly disable all resourcepacks, with this mod installed these will use a fallback and show any errors in-game and the output log:

  • Shader program compilation errors
  • Missing shader programs
  • Shader linking errors
  • Invalid or missing post_effect jsons
  • post_effects that reference invalid targets

For minecrafts builtin shaders, the mod will attempt to load the default ones as a fallback if an error occurs. For modded shaders, a dummy shader will be used as a fallback which will make any objects using that shader invisible

Additional features

  • Shader hot-reload keybind (F3 + R) which just reloads shaders, much quicker than a full resource reload
    • Works in the title screen, not just when in a world!
  • Adds better errors for some things. For example, when importing a non-existent include shader the gane will produce a proper error rather than throwing a null pointer exception
  • Added an option to disable shader linker info logs
    • Off by default but can be enabled if it causes a ton of log spam (like it does on my machine)
