[1.337b][SMP][Mod incompatibility] IC2 and Optifine

Generally,thread speaks-1.8.1,IC2,1.337b and not working smoothly with any of optifine mods-IC2 textures messed up,like generators with one-side diamond ore texture and wood-into-furnance texture changes
Don't know,If it's just for me-but I want Optifine mod badly I guess,time to scream for help
(If the topic is a double,at least link me to the solution u.u)
