I have MotoBlocks from StarsAligned Studios, and it helps me make a walk look realistic. I have a hard time with the timing of movements like walking, and turning where the hips and feet need to flow properly to look realistic, and I find MotoBlocks helps me get the basic movements down...

The trouble is that it is so limited. I usually start with a 1500 frame, or better, rough draft with that tool, that I need to cut down to 200-400 frames in order to get the movements from point A to B past obsticals. Aiming is usually a problem.

I have tried the walk designer on several occasions, but have always been turned away frusterated with the results. The last time I made an attempt to use it was with PP2010, so maybe it works better now with PP2014? If not, that seams like a good place to rework.
