Reply To: Correct normal map could be created, to represent the apparent height differences, just like the example height map. Right ?

    Hey, that image still doesn’t communicate different heights unfortunately – it’s an optical illusion that we might see but the computer cannot.  If you use a color picker to test their values, you’ll find they are exactly the same in all of those flat areas. Baking normals in Blender is the same as building a normal map in Substance Designer, the results only output angle information. However, if you combine the height map with the normal map (as you might in Substance), then you can get the best of both worlds – at the extra cost of the additional image. Hope that helps clear things up!
