I need help with my shaders. I installed Optifine 1.15.2 but not from the official website. I then used jarfix to install Optifine. But when I download shader files and placethem in my shader folder. The shader files shows up in my Minecraft shader settings but when I click the shader pack, it doesn't do anything. The options are greyed out and the shaders don't seem to be actually there or something. Could anyone possibly help?
