Distant Horizons? 1.18.2? Good luck getting shaders working. Shaders support with Distant Horizons installed starts at 1.20.1.

What changes have you made since my last message? Only removing Distant Horizons? Wait, your Minecraft version is 1.21.1 instead of 1.18.2? Apparently I confused your Iris version for Minecraft version. :yes:

so why removed DH just rework the shader??? i think there is a bug betwin DH ans Iris in 1.21.1 and i just discover it... so d'ont now probably m'y DH parametre cause they work before and when i change parameter that be broken if you need to check it there is it

If you're on NeoForge and using Distant Horizons 2.3.3-b, there's a bug in Distant Horizons that causes shaders failing to work. Your choice is to use their nightly build, downgrade to 2.3.2-b or change your loader to Fabric.
