    Question Weird Joint Orientation in Maya



    Hello guys and gals

    I would really appreciate if You could help me out with my little problem

    I am working on re-targeting tool for Autodesks Maya 2012 and I have noticed rather annoying thing

    Every time I multiply joint transform matrix, Maya is resetting my joint orientation back to world coordinates and instead it's adding those values to my joint rotation

    Is there any way to keep the orientation locked when I apply new transforms to the joint ???

    Thanks a bunch for taking your time

    What is the process that you're using for retargeting?

    Hey Brian, thanks for responding back

    Lets say that I want joint B follow the motion of joint A

    on the frame 0 both joints are in their own original bind pose although they are both oriented in their own way and on the frame 10 joint A has rotation on all axis

    Here's what I do :
    |A| = joint A transform on frame 0
    |B| = joint B transform on frame 0
    |ROT| = joint A transform on frame 10

    |B|' |A| = |REF| = transform difference joint A and B on frame 0

    |REF|' |ROT| = re-targeted transform for joint B on frame 10

    That puts my joint B right in sweet spot on that frame 10 but its orientation is set back to world coord's and instead Maya dump that orient into its rotation value


    Any ideas ??
    If You need any more information let me know ,

    Thanks again for looking into that

    Dan
