View Full Version : problem of symmetry with bones in XSI

Hello everyone,

I am now trying to make a symmetry of my skeleton, but I met problems. I used Skeleton/duplicate symmetry, but it is not perfect because of the wrong orientation of the rotation and position axis, so I used scale-1 and rotations in the neutral pose tab to get the right orientations of my axis. It works, but I have scale-1 and rotations on my neutral pose, and I don't like that.
I created a "rig from biped guide", and the bones orientations are perfect without any scale-1 on them. If anyone knows how to do, it would be really nice!!

Thanks in advance.
Pascal

Hi!

My trial ran out so I can't test this but have you tried 'freeze transform'(?) from Transform(?) -menu. It sets all transforms to 0 or to 1.

Hi

If you do a freeze transform on a null, a root or a bone, it doesn't work because of their own nature. It works with polygonal for instance, but not on this kind of object.

I am not sure if I understood correctly , but you duplicate your bones , than select all of them and do another skeleton > set neutral pose.

Works fine here and all my bones are nicely zeroed out.

No, what I did is a duplicate symmetry of my chain in branch mode by selecting the null root. But then, I want to have a symmetry in the behaviour of my bones for rotations.
But I find a solution by making negative scales on the root on the 3 axis and a 180 rotation on the Y axis if my memorie is good. It is not perfect because I still have negative scales, but the bones that supports the skin don't have negative scales, so....

Hi pascal, hummm if you have this kind of rotation, prepare yourself for problem ( like animators strikes on you with axes and guns, tank and mass destruction weapons..... maybe just angry .....) Check the doc for neutral pos, sheep factory was right.

Good luck.
