How can I add optifine to Tekkit?
I tried doing it the regular way (via adding it into the modpack.jar file in the tekkitmain/bin/ folder), but when I tried launching Tekkit via the Technic Launcher, it appeared to load the files, pop up an MC window for a split second, and then just fell right back to the Technic Launcher screen. The same thing happened on subsequent tries, as well.
Thanks in advance!
