When I first time extracted this model from sleeping dogs,I told myself it is impossible to convert this model to gta iv because UVW Map was destroyed.
I tried several times with different ripper tools but does not work,I finally made a new UVW Map for face and other parts.(I'm not a professional 3d modeler)
This model is not fully rigged from this game and reskinned.
Now you can play metal gear rising raiden and max payne 3 mona sax instead of niko.
