Baked model Outline is not affected by ClothPaint

I created a model with outlines and its not affected by the NvCloth ClothPaint. The model’s outline was created in Blender using solidify modifier to create an outer hull where the faces are inverted. Effect is then exported with the model as a FBX. The outline in unreal 4 is not part of any material, it is in the mesh itself.

Before…

…and after the NvCloth applying.
