| You can use bones rigs with Crowd, but having never done it myself I can only really point you in the right direction.
Installing CS adds two new block controllers to Max (called Motion Clip and Master Clip I think). I would presume that Crowd uses these to read bones animations, and that you create clips in the same way that you create Blocks (in trackview, expand Global Tracks--> Block controllers--> Availible etc...check the online help if you haven't used Block controllers before). After you have created you Clips I assume that crowd will handle them as it does Biped clips.
Like I say I am making some heavy assumptions here, but hopefully it will be helpful enough to get you started. |
