when I try to use the Sphax texture pack with the tekkit classic add on, some textures such as cobble, stone, tools, wood logs, leaves, glass, ect. are default textures. other default blocks have the sphax textures. Its like its missing a certain file. I've tried the 16x, 32x, and 64x. I have 6gb of RAM allocated to it and I have reinstalled both the modpack and the texture pack with add ons multiple times and it still won't work. I never had this problem before. Does anyone know a fix? I have also tried the texture pack without the add ons and it does the same thing.
