FREX

FREX is a rendering API for Minecraft mods to create content that wouldn't normally be possible. FREX is currently only available for Fabric but a Forge version is planned. FREX includes a built-in renderer (Pastel) that implements most of its features (except shaders) but it's possible to create a mod with a different/better implementation. [Canvas](https://modrinth.com/mod/canvas) is currently the only renderer that implements FREX. Renderers and mods that use FREX (like [JMX](https://modrinth.com/mod/imx)) will generally include it so you probably don't need to download and install it separately. It's listed here only for visibility.
