[Maya] Aim constraint does weird things

Ne0nfire

Hi guys, I was about to reorient some of my joints with a aim constraint from maya but it doesn't work like I wanted. This is how I tried it:

At first I ungroup the two other connecting joints,
then I set the joint orientation to zero and at the end I select the child first
and then the joint that I want to reorient,
now I apply a aim constraint with these settings:



Now it gives me almost the right result except that the joint is kinda 45° rotated, do any of you know why?

To fix this you should use a aim object. in world up type, select Object UP. then create a locator and put its name in World up object.

Then move this locator and the joint will aim correctly.

But its easier to manually rotate the joint using the joint orient x, y or Z.

At the picture, your joint seams to be rotate 45ishº in X. just put a 0 and done.

I had to put it to 90 from 138~ .. now it points right



but I still don't understand why it's rotated after the aim constraint.
Is something wrong with the values from the child?
