Using Adobe Mixamo Fuse CC (Preview) With UE 4.11 (should work with 4.10/4.12 as well)

Can you make a tutorial on how to rig multiple animations?

For example the magic locomotion pack + 1 attack? How would go about rigging those? From idle to running isn’t a problem for me, it is the crouching/moving left/moving right/attacking, that is the problem.

There are no tutorials on Youtube on how to do this as far as I know.
