I have installed shader and in the folder I use the badlion client but I have no menu where I can choose the shader what can I do
Do you have Optifine?
If you don't MUST have it, otherwise the shaders won't work!
Do you have optifine? And if you take version 1.16, blc net works because they can do an optifine update
BAC = BLC = Badlion Client = PvP Client so yes optifine has but thanks
Ah thanks for the info explains a lot
