Zigfu character facing Z+ instead of Z-, urgent !

hello,

I've installed zigfu and the captation is going pretty well except than the character player is facing the wrong direction. By default the character is facing the Z+ axe and some of our games are made for a character facing Z- axe. I tried to parent the object containing the zigskeleton component to a null gameobject and rotating the null object by 180° but weird things happen, like a miror for movement, but the character is still facing Z+ , and i ddin't see a orientation parameters ( like the position biais on zig skeleton). Rotating the whole world instead of rotating the character will be a heavy mess of work, since we got things working in world coordinate. Our pipepline is only using Javascrip, no C#.So is there a way of rotating the character so it faces Z- ?

thx in advance.
