How to mirror animation on a character in XSI? 2005-03-01 - By peterb
Back
I just went silly and tried to do this, and it could be made to work:
made some fcurves on the right arm, on a default skeleton.
Saved this out as a clip
Inserted the clip on the mixer.
Right button on the clip > source.
there you find all the fcurves by name, in a list.
replace the L's by R or vice versa.
delete the clip, and insert it again. (it doesnt update on the fly...)
And magically the animation now sits on the other side of the skeleton.
there's probably a better place to do this.
downside: none of this logged in the script editor!
and this will affect the source clip, which is not very clean too.
then with the clip selected in the mixer, goto clip properties. You get
again the fcurves by name, last collumn is called clip effects. Her you can
type an expression, ( "-this" inverses the current animation) that will be
added as a clip effect (yellow line in the mixer)
Downside: this has to be done for each clip!
However it logged into the script editor, so you could find out how to
script this.
This could be part of your synoptics view, since would be dependent on the
rig...
hope this helps some?
