FREX
by grondag
FREX is a Fabric and Quilt rendering library that lets other mods create content that vanilla rendering cannot produce.
What it does
FREX provides a rendering API that other mods call to build visuals beyond what Minecraft offers by default. It ships with a built-in renderer, and the Pastel renderer implements most of its features except shaders. Mods that use FREX generally include it or list it as a requirement, so players usually do not need to install it separately.
FREX is client-side only, so only the client needs it and servers run without it. The library is published for Fabric and Quilt across nine game versions, 1.18.1 – 1.20.2, and is open source under the GNU Lesser General Public License v3.0 only.
