Saw that video recently and like the motion, but using search function for "DDD" only finds 16 videos. Is there another name to search for, or is it just not a very popular motion?
I'll be of no help with this, but you seem to at least know A place to look from. Is there like a library for all these generic motions to pull from?
Not really that I know of, there's so many songs that MMD typically use now. I usually just end up seeing one I like, searching that in the search box here and going through all of that.
