[RPT] Resource Packs Tweaks

by Danrus110_

[RPT] Resource Packs Tweaks gives resource pack authors extra options for item models, built on the [RPF] Resource Packs Fusion library.

FabricQuiltClient-side onlyMIT LicenseOpen source1.21.6 – 26.2

What it does

The mod adds a set of tweaks for item models in resource packs, so authors can shape how items are drawn without writing every model by hand. It requires [RPF] Resource Packs Fusion, which supplies the underlying library the tweaks depend on. Players who only use a finished pack do not interact with the tweaks directly; they see the results in the pack's item textures and models.

The feature set covers a templates system for reusing model structures, a variables system for setting values once and referring to them across files, and regex custom flags for matching item names in model rules. Arm animations are included as well, along with further smaller additions. The author points to the [RPF] Resource Packs Fusion documentation for ways the two mods can be combined.

The mod runs on Fabric and Quilt, is client-side only, and is published for 26.2 as the latest file, with builds covering 1.21.6 – 26.2. It is released under the MIT License and is open source, with public source code, an issue tracker and a wiki.

Key features

  1. Templates system

    Reusable model templates let an author define a structure once and apply it to several item models.

  2. Variables system

    Named variables store values that item model rules can read, so a change needs editing in one place.

  3. Regex custom flags

    Custom flags accept regular expressions, letting rules match groups of items by name pattern.

  4. Arm animations

    Tweaks for how items are held and animated in the player's arms are part of the feature set.
