Hello, I'm trying to merge mods but I can't seem to get them all active. I downloaded Curseforge and Fabric and no success. I try to put BetterEnd / BetterNether and Alex's mob to start and it's impossible.
Then I try to put Complementary Shaders v4 on Optifine or the Iris and nothing either.
I'm lost between all the apps and tutorials, please help me
