Since there has been much discussion regarding this topic and how to make them properly, I submit this. It has been repeatedly pointed out that the GIMP and PhotShop plug-ins "normal map" and "bump map" do not project onto a sphere. However, if a texture has been created that already is mapped to a sphere, wouldn't simply applying either plug-in to the texture create the desired effect when rendered in Celestia?
Sorry for the wordiness...the coffee is being especially effective this morning!!!!
