I Saw many tutorials here and in Youtube about creating custom animations... put the problem is that I donīt understand them!

I use Halo Animation importer, and CAD animation exporter, I donīt use Blitzkrieg because my 3ds max reject it. So everytime that I replace some marine animations with mine animations with kornman00 animation editor, I get the same result "NOTHING" The marines still moving normally and no how I want. PLease help :(
