ResourceToggle

A toggle button sits in the top-right corner of the title screen and the pause screen. Pressing it switches resource packs, and a hotkey under the Controls Misc category, unbound by default, does the same. An action bar message confirms each switch. The mod targets testing and debugging of resource packs, where a developer compares a pack against vanilla textures repeatedly.

The mod is a client-side mod for Minecraft 26.2, published for Fabric and NeoForge. Only the player's client needs it; the server never sees the switch, and packs are accepted on arrival. Two options, extraKeepPacks and extraExcludePacks, let the player decide which packs stay loaded or are forced out. A keep mod-provided assets mode can be set to vanilla-only, and that mode is required for the switch to work as described.

The first switch in a session takes the full load time, and memory use rises with the number of packs and textures in play, so GPU and RAM demand is noticeable on large packs. Switches made afterwards load from memory and finish in a fraction of the time of a standard reload. The mod is released under the MIT License and is open source, and its source code and issue tracker are public.
