I helped make 2 of the razor wire kits. I modelled the primary heights and normals then Matt Dirks took those and dropped them into designer to add params and other maps. I also made a tutorial to show how I go about using these textures to make models games.
In the video I go over how to go about mapping trims like these planes and positioning the geo for export to a game engine.
