PackForge – Optimized Resource Pack Loading Time

PackForge

PackForge is a client-side Fabric mod that helps large resource packs load faster.

It is mainly designed for big server resource packs, such as packs generated by ItemsAdder, ModelEngine, and other heavily customized resource packs.

Minecraft normally has to search through the resource pack many times during loading. With very large packs, this can make the loading screen take a long time, especially when the pack contains thousands of models, textures, sounds, or JSON files.

PackForge improves this by building a fast internal index of the resource pack when it loads. After that, Minecraft can find files much faster instead of repeatedly searching through the whole pack.

What PackForge does

• Speeds up loading and reloading of large zipped resource packs
• Helps reduce long loading screens when joining servers with big packs
• Configurable features such as:
  • Skip loading fade out
  • Loading time toast
  • Each individual features

Atlas Overflow Protection

Some very large resource packs can also fail to load on weaker or older GPUs because the final texture atlas becomes too large.

PackForge includes optional atlas protection that can downscale oversized textures in memory so the pack has a better chance to load successfully.

PackForge does not modify your resource pack files. Atlas protection only creates smaller temporary versions of oversized textures while the pack is loading. Most normal block and item textures should look the same during gameplay, but heavily downscaled textures may appear slightly softer on lower-end hardware.

This feature can be disabled in the mod’s config file or via ModMenu’s config screen
