It's for a skinned character. I'm thinking more of a run cycle for bipeds because a biped runcycle can be loaded into any skinned character with bones so I can use it on mmost human like characters in 3Ds max
Looks like some clarification is needed in this thread. Biped is the 'bones' system used by Character Studio, a Max plugin (A highly integrated Max plugin). You cannot load a biped runcycle into just any character with bones... but you can
load that runcycle into any character that has a 'biped' rig.
Now, it's been a while since I used Max (I switched to Maya around version 7), but I do remember that Character Studio used a different spline editor, it's own UI, and required a very different approach to animating. Then
you were faced with the challenge of non-linear animation using motion clips if you wanted to re-use that anim (I can't remember what that was called... Motion Mixer or something?). Basically, Char Studio had many advantages and features, but it wasn't fun to use.
Now, things may well have changed in the later versions of Max, but the question is - Are you looking for specific
tutorials on animating the biped rigs using Character Studio? If not, then a general animation tutorial on walks will be useful to you. If it's just that you don't have a custom rig I'd suggest that you download a free character and play around with that. There are plenty of free rigs, (Lowmax is a great starting character) and it'd be better, IMO, to learn to animate a custom rig, rather than get buried in the additional challenges and technicalities of Character Studio.
