Hello guys I hope u can help me. I got some troubles right now with shader mods. Im not the expert of minecraft modding. Aswell i didnt find any information how to launch shaders on 1.7.10 hexxit. Just for older versions. Now my question, i follow most all of the old parts (older versions installations) I follow there the instruction about adding gsl mod and optifine adding on the modpack file. So... after i did my game just try to load, or lets say the launcher trys to start the game, nothing happend ^^ Can u guys help me maybe? Would be awesome to play with shaders Greez Jesche
