WynnIris
by LordGonner
WynnIris is a Fabric fork of Iris Shaders that adds built-in Wynncraft shader effects, and it runs on the client only.
What it does
WynnIris renders Wynncraft's glint effects, custom skyboxes, translucency and player emotes directly through the shader pipeline, so effects such as tints, rainbow glitch, shadow and aurora glints appear under shader packs. Glowing eyes and other emissive textures are lit per pixel under shaders, and emissive mobs follow the same path, while Fruma spell effects render with correct transparency. Scene darkening and fog from packs such as Memory Mist and Stormy War Red Lightning are integrated as well.
The mod works as a drop-in replacement for regular Iris: it reads the same config and shader pack folder. Forward packs such as Complementary and BSL, and deferred packs such as Photon and Solas, are supported, along with Distant Horizons and Voxy. Outside Wynncraft the behavior matches Iris, and players who do not play Wynncraft can keep using regular Iris instead.
Installation needs Sodium on Fabric. WynnIris is published for Fabric only, for Minecraft 1.21.11, and it is released under the GNU Lesser General Public License v3.0 only, so the code is open source and the source and issue tracker are public.
Key features
Wynncraft glint effects
Glints such as tints, rainbow glitch, shadow and aurora are rendered natively through the shader pipeline.
Region shader profiles
Ambience packs map shader configurations to Wynncraft regions, and the mod switches profiles automatically while traveling.
Region editor and presets
An in-game region editor lets players draw their own zones, and a preset system saves tweaked settings per profile.
Prewarm cache
An optional prewarm cache setting aims for instant transitions without stutter, avoiding the reload delay of manual switching.

What the author says
A fork of Iris Shaders that makes Wynncraft's visual effects work with shader packs. Drop-in replacement for Iris, uses the same config and shader pack folder. If you're not playing Wynncraft, just use regular Iris. WynnIris does nothing outside of Wynncraft.
