I made a very simple Skeleton setup, Two Joints on the right side and two mirrored joints on the left side. Root joint is in the middle.
I the Physics Asset Editor, i have done the setup for the right side and I would like to mirror bodies and constraints to the right side, if I select the bodies and press “M” or click on the mirror button, nothing happens.
Is that because Phat does not know how to find symmetry? or its a bug ?
Mirror is really poor in Phat, always has been. The problem you are having is Mirror only works if the exact naming convention is used: Bones MUST end in _L and _R (eg: Arm_L and Arm_R) for it to decide there is a symmetrical pair. Basically it doesn’t find a symmetry at all, but looks for the paired named bone and (in theory, but rarely in actuality in my experience) creates a similar physics body across the vertical axis with flipped constraints.
