Geoset Merging Problem

I've geoset merged Medivh's head the the Demon Hunter's body.
W3 Viewer shows the model fine, but when I use WE or in-game, the model is headless.
The MDX is attached.
(I'll alpha out that piece of hair floating in the back, when I skin the model)

ok on the bone of the head you're using Parent 171...you have to use the ObjectId 47. so it should look like this

Groups 1 1 {
Matrices { 47 },
}

try that....

Well I'll be damned, my first geoset merging works! Thanks!
Hmm...how do I know which bone to use? just use the first one which uses the head as a parent?

i believe so...trial and error my friend that's what i do...but i'm sure Cookie could tell you more...
