Use this morph, these conforming quills and whiskers, and the included Look at My Hair preset to turn the Genesis 8 Female into an adorable hedgehog. Really, the most adorable thing I've ever created. Both Iray and 3Delight materials are included. Man, she's so adorable.
In regards to LAMH, when rendering in Iray you should save the addition of hair to just before render time and be sure to set the geometry type as "export to obj" and not "Render Man". When rendering in 3Delight, "Renderman" is still the way to go.
