does anyone have a minecraft.jar with the shaders mod already installed because i'm a failure at installing that
i'm going to make this REAL simple for you so your inevitable excuse why it didn't work/was too hard is complete and total bullstuff:
1.) download the FTB launcher directly from here:
http://www.creeperrepo.net/direct/FTB2/43578b7c5c73be3640935b94825e5054/launcher%5EFTB_Launcher.exe2.) boot it when it finishes downloading, ensure everything's up to date (java etc)
3.) you'll see five tabs on the top of it. you should already be at "ftb modpacks", stay there.
4.) partially scroll down until you see "FTB Horizons".
5.) a little button called Edit Mod pack is near the top below the tabs, click it and "add mod" on bottom right. add both optifine and the shaders mod you're using for 1.6.4. disable ALL other mods except forge, add anything you might want.
6.) play.
