Vertex Normap Map Issue

[Steel]

Hello.

I´ve imported some .obj which has gotten some normal map done in ZBrush.

When i open it there is a vertex normal map included. But i need the object in subpatch mode to use in Layout. Works fine so far
when i render object with 89° Smoothing aplied with native Lightwave. But when i render same object with kray i got lack of smoothness.
How could i fix the object to get it work with subpatch applied and a working smoothing surface?

Hello Januz. I´ve checked it again. I think its not the problem with the vertex normal map, it´s problem with the image based normal map. If i find out that there is different treatment between LW native and Kray i will post scene/object.
