Hello, I have a sequence of movements that are done with the right arm. The animation is 1144 frames. I basically key the right arm joints at various frames and interpolate for the rest:

For the whole motion, the left arm and everything else is fixed.

I would like to generate a new motion that is the exact mirror of this one.

I noticed that if I use Pose Symmetry -> Swap right and left, that it is only valid for one frame at a time. I thought that maybe swapping every key frame would work, but it does not fully mirror the motion.

Is there a way to do this automatically without too much labor?

Thank you.

This litle script may help:

import sys

if sys.version_info.major > 2:
    basestring = str
else:
    range = xrange

SCENE = poser.Scene()

SWAP_FUNCS = ["SwapTop",  # 0
              "SwapBottom",  # 1
              "SymmetryLeftToRight",  # 2
              "SymmetryRightToLeft",  # 3
              "SymmetryBotLeftToRight",  # 4
              "SymmetryBotRightToLeft",  # 5
              "SymmetryTopLeftToRight",  # 6
              "SymmetryTopRightToLeft",  # 7
              ]


def do_swap(actor=None, swap_function="SwapTop", keysfromscene=0, startframe=1):
    """
    :param actor:
    :param swap_function: String, name of the function to use.
    :param keysfromscene: Use framekeys from global scene or local actor. 1 == scene, 0 == actor.
    :param startframe: Frame nr to start (1 to n)
    """
    if actor is None:
        actor = SCENE.CurrentActor()
    figure = actor.ItsFigure()

    if isinstance(swap_function, int):
        swap_function = SWAP_FUNCS[swap_function]
    if isinstance(swap_function, basestring):
        swap = getattr(figure, swap_function, None)
        if swap:
            SCENE.SelectActor(actor)
            nextframe = SCENE.NextKeyFrameAll if keysfromscene == 1 else SCENE.NextKeyFrame

            framenr = startframe - 1
            while framenr is not None:
                SCENE.SetFrame(framenr)
                swap(0)
                framenr = nextframe()

            SCENE.DrawAll()


if __name__ == "__main__":
    idx = poser.DialogSimple.AskMenu("Select", "Swap method to use:", SWAP_FUNCS)
    if idx is not None:
        do_swap(swap_function=idx)

Simplest use: Select actor/figure you want to work with.

Start the script. It will ask for a methode you want to use to swap. For what you decribed, you may want to use "SwapTop". The script selects all keyframes inside the selected actor and performs a swap.

Thanks! I think Swap Top worked pretty well. Only thing I had to manually do was then delete the old key frames for the opposing side and then change the interpolation type to linear, to preserve what I had before, since default is spline.

The code is simple enough to where it can continue to help me understand Python and the Poser methods.

I think that Pose Symmetry - Custom allows you to specify a frame range ... IIRC.
