As long as the whole pipeline is there. I mean, you gotta be able to generate, export, then re-apply that normal map to get the savings in polygons. But I guess this DOES do the re-import, because Carrara will render the normals data already (I know, because I rendered out ALL the alpha channels while I was generating a picture and bump for the texture on something else.) If it can be as simple as generate, save, import material, apply, it could be a saver every time a scene gets a little large to handle.
