Thank you for the response once again, this gives me something to work on over the Christmas break ;-)
Just to be clear, when I said 'nothing displays' what I meant was the Moon renders the surface bitmap, but the normalmap does not seem to be applied - the craters are not shaded along the terminator. When the movie is displayed in CS4 the normal map is applied correctly. I am using the [Embed(source="LALT_normalmapV2_2048x1024.png")] construct to load the files into the swf file. I have a very nice 5760 pixel bump map (and the same size tangent nomal map), though I am having to scale down the bumps in Photoshop to make them more realistic.
