Hi there. I UV'ed this model in Wings and then generated normal maps from a hi-poly subdivided model (tangent and object space NM) in xNormal. In xNormal it looks perfect but I wanted to see how at least any of the NM looks in Wings 3D. I dragged the image onto the material, picked bump map (normal map) and you can see the result below. I'm not expecting that they look similar but I'm showing the xNormal pic. only as a reference for the model curvature. In fact in Wings I wouldn't want my model to look shiny and all, I just want NM to make it seamless to see the bare effect of NM.
