View Full Version : Problem with joint orientations...

I made a leg, duplicated it, SCALE # -1 to the other side. Normally it works fine, but this time when I rotate a joint, it rotates in the opposite direction. I want X to rotate in a positive direction but instead rotates in a negative direction.

Solution?

You could mirror the “JOINTS” not by "duplicate" but by "Skeleton->Mirror Joint". Mirroring joints by "duplicate" is not a good idea.

the problem with mirroring joints is that if you've done some set drivenn keys or something like that, then you'll have to re-do them... (which sucks)

Use MEL instead to build the whole skeleton :eek:

You can try and change the local rotation axis for the joint. Select the joint and go into component mode. Right click over the "?" botton icon and be sure the "local rotation axis" has a check mark and is available. You should now be able to select the joint and rotate the axis without rotating the joint itself. Now when you go back to object mode, the joint will rotate as you want it (hopefully).

If you use the mirror joint tool you shouldn't have this problem. (In regards to SDK stuff...you'd wanna do that last anyways once your skeleton is good and the way you want it.) Cuz yeah...you can't mirror those SDK's. I think there are ways around this...but kinda a hassle.

I´m conform with my pres ... plus:

sting to re-auto-orient-joints: "joint -e -oj xyz;"
to flip axis in lokal axis mode: "rotate -r -os 180 0 0;"

... to be executed in the command line (without quotes).

I tried doing this for a prob I'm having. I went to display|component display|Local rotational axis, I have the "?" checked and everything but it still rotates the joints lower in the hierarcy, any advise? I'm using Maya 4.5
