So as you see in the title i have been trying to add Buildcraft to Voltz. What i did was go in to C:\Users\Erik\AppData\Roaming\.techniclauncher\tekkit\mods and take all the Buildcraft mods out of there and then add them to C:\Users\Erik\AppData\Roaming\.techniclauncher\voltz\mods.
When i launch Voltz the Buildcraft items are not there.
I am probably being noob about this but help would be appreciated!
