    Howdy,
    Is there a way to calculate how much of an effect an individual bone is having on a point in an object? Ideally this would be a percentage as compared to all the other bones affecting the point. Also, this would need to work with vertex maps/CB maps.
    Where in the SDK would I look to find info on things like this. A search for bone and deformer turned up very little for me.
    Thanks,
    Donovan Keith

    There are no special functions for bones in the API. (Thus the lack of descriptions of such functions in the docs.) All you can get is the end result, I'm afraid, and the raw parameters for each bone. Previously people have been asking for the bone algorithm but that isn't public. You'd have to reverse engineer that and then combine it with the vertex map information.

    Gotcha. Thanks for the info. I can think of a way to calculate the information (move all bones individually, calculate point offset in deformed and predeformed mesh), but its a bit brute force and ugly for anyone other than me to have use for it.
    Cheers,
