I can't download this, but I'm going to use it as a reference. Is this the right look?

I plan on using male_basic max as a base, and export it as a single animation. You should be able to use the M25 keyframe transfer tool to add it to almost any character that uses male basic. I'll do a female one also. Does that work for everyone, or should I make it with a whole set of basic animations?
