There doesn't seem to be a tab for it in the launcher under Edit Mod Pack. Am I doing something wrong? I was wanting to install Optifine and GLSL Shaders Mod by putting the shaders files in the .jar into the optifine.jar and putting it into the InstMods folder and then activating it in the JarMods tab like I did with the other modpacks... but that tab isn't there for Tech World 2. Is there still a way to do it?
