Shaders won't load at all on 1.21.1 [Fabric 0.16.10, Iris 1.8.1+1.21.1]
I've tried a couple different shaders [Complementary Shaders - both versions & Mellow by TheCMK] with this modpack I made today but nothing seems to be working, wouldn't apply the shader both before and after installing a custom skybox so I ruled that out as a potential conflict
This was the error it gave me, I'm not mod-savvy enough to know what it means so I'm sorry if it's an easy fix LMAO
net.minecraft.class2973: Invalid shaders/core/basic.json: Non [a-z0-9/.-] character in path of location: minecraft:basic_tessControl.tcs
