Legacy Resource Pack Adapter

by Plugbomb_Cairo

Legacy Resource Pack Adapter restores loading of older resource packs in Minecraft versions newer than the one that dropped them, where packs in the earlier format stopped being recognised.

FabricClient-side onlyMIT License1.20.1 – 1.21.6

What it does

Newer versions of the game no longer read resource packs written for the earliest releases. A texture stored at an old path, such as textures/blocks/yellow_wool.png for a yellow wool block, is ignored, and only the newer textures/block/yellow_wool.png path is picked up. This Fabric mod brings back support for those older packs. It is client-side only, so only the client needs it and servers run without it. Builds cover 1.20.1 – 1.21.6, and the latest file is 1.0.0 for 1.21.6. The mod is released under the MIT License but is not open source.

Key features

  1. Old texture paths

    Textures stored under the older directory layout are read again, so packs display the blocks their authors intended.

  2. Legacy pack format

    Resource packs with a pack format below 4 are accepted, which the game otherwise rejects on newer versions.

  3. Older packs stay usable

    Packs from the earlier releases load alongside newer ones without any changes to the pack files.

Questions

Does Legacy Resource Pack Adapter need to be installed on the server?

No. The mod is client-side only, so only the player's client needs it.

What the author says

Minecraft 1.19.3 dropped support for resource packs for 1.7-1.12. For example, 1.19.3+ won't recognise textures/blocks/wool_colored_yellow.png for a yellow wool block. Only the new path, which is textures/block/yellow_wool.png, is recognised. This mod brings back old resource pack support in 1.20. The resource pack…
