@JackplaysMC :p Yepp there you have it. 1: Make a cleaninstall of 1.7.10. This means delete everything from .minecraft but not saves launcher.jar launcher.pack.lzma launcher_profiles.json options.txt servers.dat Then retrive a new copy of 1.7.10 by running 1.7.10 once. 2: Install optifine: Just click on the optifine.jar and run 1.7.10_Optifine once. 4: Getting shaderpacks: Make a folder called Shaderpacks and place it in .minecraft. All shaderpack zip's goes in to that folder. Note thats not the basemod. Shaderpacks are zips not jars. 3: Install the shadermodcore: Click on the shadercore.jar and select 1.7.10_Optifine_Shadermod in your profile. In edit profile disable launcher visiblity. Ugh it might me short but I got irl things to do :P
