with coolfile's animation importer and the normal w3d importer I combined both tools to only one over 1 year ago.
With this scripts you don't have to load 2 different scripts! It's a big advantage and even better to handle!
with Help function included (note: the help "load w3d skeleton + animation" isn't correct. It is supported but I didn't know that in this time.

go here!

//EDIT: it works still with 3ds max5 (I don't know with a higher version, too)
