How can we mix motions without Motion Director?
I have 2 motions that I need to blend together where a character is walking forward and then swings a weapon while he is still walking. 
The walk and the swing are 2 different motions. I need the swing to occur while he finishes his final 2 steps. I used to know how to custom import into the MixMotions tool but that seems to no longer be a feature.
Until we can custom import walk iMDs, how can we mix those motions together?
