Thank you!

Yes:

        vec[0]+=(cop[0]-co[0])*weight;
        vec[1]+=(cop[1]-co[1])*weight;
        vec[2]+=(cop[2]-co[2])*weight;

Looks like co is bone position before transformation, and cop is after it.
So in exporter I need to read weights for vertices and transformation of every
bone in every frame.
