Biped to AWD
1°/ Create your biped in 3dsmax
2°/ Create simple basic bone (in right view to keep good orientation), the red one is the root at 0,0,0
3°/ Align your bones to biped object like that
4°/ Go in hierarchy select ‘Affect Pivot Only’ and align white final bone to biped like that and delete them
5°/ Now go to Animation menu and add position constraint and orientation constraint for each bones to the good biped part
6°/ Do the same for head, chest and pelvis (size of bone is not important we adjust skin enveloppe after)
just need it taller than wide or the envelope will be horizontal.
7°/ Same for hand, foot. you should have somthing like that, Is minimal best setting for human
8°/ Test some animations to see if all in place (the red one not move and stay at 0,0,0).
9°/ Add some optional extra bone for finger and toe same thechnic
10°/ Great, now we have all bones ok but there are all independent, if you export like that that didn’t work so.
11°/ You have to link bones like that, the double click on red select all.
12°/Add all bones to skin modifier without the red. Adjust the pelvis and chest envelope for best result.
13°/ That’s all now you can export and use biped motion mixer for your animation.
