Quote - "weight-mapping (which REALLY helps with animations!),"

Can you explain exactly how weight mapping improves animations?

Also anyone have a link to where I can get V4 Weight mapped version?

Cheers

The V4 weight map injection script is available from RDNA:

Or PoserPlace:

I can't comment on the animation side... and have only a limited experience using the "untreated" V4 in any context to be honest. But the weight mapped version is much nicer, and more flexible, to pose... or so I've found at least, with what I'm doing with it...
