Hi guys, I made a character in Houdini (with its test geometry), I mirrored left limbs skeleton to the right,
For example, right limb bone’s orientation is mirrored to left limb. You can see that on joint’s pivot. In this case, Houdini alines joint’s Z axis to child, and X(in red) and Y(in green) are used for joint rotation(limbs can rotate on two axis)
When it is imported to UE obviously joint’s orietation becomes non-axis-mirroed
After that, when you drag&drop a should module and arm module on two limbs, you see that the left arm is ok when IK is on, but right arm is f*cked.
Theres obviously nothing to do with skin, in Houdini two bone’s chain IK is working.
I tried to resolve this with primary axis/secondary axis setting, I find that even if I reverse the primary axis, when IK target is not moved, it seems ok
However, it you only move one milimeter, you will find that things go wrong,the shoulder rotates to wrong direction, even its rotating pivot seems get rotated
Anyhelps?
