Iris core sharers compat fix
Iris core sharers compat fix is a small experimental Fabric compatibility layer that lets Iris shaderpacks render objects drawn by mods that use custom core shaders.
What it does
Normally, objects rendered by added mods through custom core shaders come out completely black when Iris shaderpacks are active. This layer tries to make Iris handle those custom core shaders so that the affected objects render correctly alongside the shaderpack. The result is described as rough: the internals are not polished, and the output looks less right than ideal, though it works in most cases tested. The mod requires Iris Shaders and is published for Fabric, for 1.21.1 only.
Key features
Custom core shader support
Attempts to make Iris handle custom core shaders that mods add, so their objects are not drawn black.
Shaderpack rendering
Lets objects from added mods render alongside active Iris shaderpacks instead of disappearing.
Experimental fix
Born out of necessity, the layer works in most cases tested, though its internals are not polished.

What the author says
This is a small and experimental mod that attempts making iris behave and not completely nuke all custom core shaders added by mods. Normally when iris shaderpacks are active, object rendered via custom shaders added by mods will render completely black.
