I am doing some skeleton weighting over here. I came to the hands. I am noting each individual bone, in the hand. My overall question is Is this necassary? . Does each indiviual bone in the hand need weights, I know that all the bones in the face don't need weights unless animations are needed. I am assuming this holds true with the hands.

If each individual bone is not need to be weighted, Which bones do Io weight....Thanks in advance.

The only bones you really "need" on the hands are the radiusX and hand bones. If you want to weight each finger individually then it's a little more involved but not complex

My example uses the right hand

r_d1_j1
r_d1_j2 < Right Thumb, with each individual joint marked _j#1-3
r_d1_j3

r_d2_j1
r_d2_j2 < Right Index
r_d2_j3

r_d3_j1
r_d3_j2 < Right Middle
r_d3_j3

and so on for the ring finger and the pinky, just weight each "joint" to it's respective part of the finger.

I havent found any real need to do this on the half dozen models I've gotten in-game thus far as it doesnt seem that those bones are used much if at all in game. So you can get away with just the radiusX and hand bones

Oh, anything marked _eff appears to be useless, I really would like to talk to their lead animator about this skeleton, perhaps I should write him an e-mail :)

actually i think the _eff's are there to be able to move the first bone. because youll notice that when you select a bone and move it, it actually moves itself and the next bone in line.

and i always weight each finger, it doesnt take that long, i just group select verts and assign the weight. i think its more professional.

While experementing with facial animation I havent found any use thus far for the _eff bones on the face, perhaps I'm wrong but so far so good, that's a good question though

As for being more professional, ok, but I really dont think the game actually uses thoes individual bones in game

i know they do, you can see them in use easily with the reaching out taunt animation. and i think you can see them with force push, and possible force grip, and im sure theres more.

My hands seem to do that too even without them weighted individually, You may be right though, I'll revisit that when I'm finished with the face

The EFF bones (or end effectors) are there for creating the actual animations of a model. Instead of rotating a certain bone, you can drag the eff to the position you want. Nothing is ever actually weighted to this bone, it is a dummy, just there for creating animations.

In regards to fingers, I usually weight each one properly.

Thanks Major, being new at this I wasnt sure what the eff bones did.

I'm gonna try weighting the fingers seprately like you guys suggest, it's easy enough to do that there isnt really a good reason not to do it :)
