About this Mod

⚑ InstantReload

InstantReload is a lightweight client-side Fabric mod that improves resource pack reload performance.

Instead of rebuilding every texture atlas whenever a resource pack is toggled, InstantReload detects what actually changed and reloads only the affected atlases.
This reduces lag spikes, shortens reload time, and keeps the vanilla reload lifecycle intact.

The mod is fully client-side, safe by design, and automatically falls back to a full vanilla reload if any inconsistency is detected.

πŸš€ When Does It Help Most?

  • Toggling resource packs that modify only a few textures
  • Development workflows with frequent reloads
  • Large modpacks where atlas rebuilds are expensive

βš™ Compatibility Notes

InstantReload modifies the atlas reload pipeline using mixins.
It may conflict with other mods that:

  • Rewrite or cancel the resource reload pipeline
  • Replace or heavily modify atlas management logic
  • Inject into texture stitching or atlas creation methods
  • Implement their own texture atlas optimization system
  • Override async resource reload behavior

In general, it should be compatible with most mods that do not directly alter the texture atlas rebuild process.

🧩 In Short

InstantReload makes resource pack reloading smarter and smoother
by updating only what changed β€” nothing more.

Frequently Asked Questions

Does InstantReload need to be installed on the Minecraft server?

No. Modrinth marks InstantReload as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does InstantReload require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.1, 1.20.1. Files for different loaders are not interchangeable.

InstantReload is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
