Highpoly made in 3dsMax + Zbrush, texturing made in Zbrush, lowpoly and maps baking made in Topogun, maps composed in Photoshop and rendered in Marmoset.
thanks for the help Mop, Firebert, Harbringer and Malcolm. It turns out that it was the highpoly that was the problem. so what i did was reverse the normal and rebake.
