Ambient occlusion maps affect lighting. SH4 doesn't use bump maps, it uses normal maps. A bump map can't be converted into a normal map, unless it's been normalised or you'll get weird artifacts. Do a google search on normalising a bump map. There should be an nvidia dds plugin to do it with phtoshop.
