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.
🚀 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
⚙ 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 — nothing more.
