Normal Map

[fishapotamous]

Hello,

  I've created a substance for some stylized vertical walls that has some copper, paint, and dirt on it.  When I started to merge my materials, I had the normals blend with the material blend, however, it produced a weird effect with transparencies. To make it work, I ran the normal map I generated earlier in the pipeline to the final normal for the output.
  Is that what I'm supposed to do, or did I miss a step in combining the materials?

  I attached the weird normals and the substance I'm working on.

Thanks
Bryan

This looks like the alpha channel of the normal map. When you use the normal filter, it stores the heightmap in the alpha channel of the normal, you may have to disable the alpha display in the 2d view (little icon at the bottom) to see the actual normal map. You may want to save it a a tga to make sure the alpha channel is handled properly.
