For a sphere and many other geometrical shapes yes, in theory. That's what Stuart class is doing in case of the sphere. In the practice, depending on size of the map, you get artefacts because you can't draw smaller than a pixel and flash tends to use nearby pixel info when the map is blowed up.
Prefab has 3 weapons against this: - you have a blur option, in case of a sphere, it would not be a problem use 2 or 4 on a bigger map - you can render at bigger size and export at desired size, plus you have a little preview where you can inspect the results right away - thx to Mario, we have a bleeding of colors filling up the regions arround the traced area's. note that for your moon, you can also load a bumpmap, it will alter the map as well. in this case, no need to load the highres file if you have a good bumpmap available. > Now I have a problem that the normal map shading shows up fine in the > CS4 IDE preview, but when the movie is viewed in a HTML container (Win > 7 Gadget), it does not appear at all :-( I'm not using this system (and never will) but are you sure its related to it? One blind shot at the cause might be the url if you use external sources. Are you sure the to be loaded sources are at the right location? If you see nothing, it often points at a fatal error like this.
