| You can't layer normals in the same way that you layer pigments,
| because, as you say, one overrules the other.
|
| You can use an average normal_map, like this for simple blending of two
| normals:
|
|   normal {average
|     normal_map {
|       [0.5 Norm1]
|       [0.5 Norm2]
|     }
|   }

Yes, thats what I was looking for. I was already thinking of creating
heightfield do this. But this works like a charm.

Thanks!!
