How to mirror joints with preserving local axis orientations

Silverland — Mon, 13 Nov 2017 00:20:17 GMT

I need to mirror arm joints chain from one side to another when i mirror then local orientation of the bones on the mirrored side is messed up and doesnt matter what settings i use its always messed up. And once it mirrored its no way to fix it and make perfect by using sceleton-orient options it will not match up exactly. So what i want is to mirror it with preserving perfect local orientations of joints.

if you want to do that, then when mirroring skeleton go to its settings and choose "orientation" instead of "behavior" then you will get the same orientation.

It's weird that it has a transform5 node above the clavicle. Can you try selecting transform5 and do Freeze Transformations and then see if it let's you unparent the clavicle without recreating another transform node above it?

If that works then try to temporarily parent the clavicle to the top spine joint and then do the mirror and see if it mirrors correctly.

If none of that works then you can post your Maya file if you want and I'll take a look at it.

Thanks. Actually i was able to successfully mirror it after two of the steps suggested by you. so i didnt follow this " temporarily parent the clavicle to the top spine joint " but it was enough and everything works.

One more question what is these transform nodes while rigging? are they bad? do i have to delete them all the time? Because they created automatically quite often. If they bad then how to avoid from creating them?

Thanks

i have found why and at what point this transform group created. so its created automatically once i parent clavicle bone to spine bone. once i do that my clavicle bone goes inside of that newly created transform group. is this bad? how to avoid that?

I think it might create the transform node cause something has/had scale values. Try to freeze transformations on everything and see if it stops creating the extra transform when you reparent.

It depends on what you're using the rig for, but ideally you'd want everything to be clean with no extra nodes. Especially if it's meant to be exported to a game engine.
