It should be possible to object-space normal mapping (also known as dot3 bump mapping) in a shader. Most normal map tools are geared for tangent-space normal mapping, which requires extra information to be provided by the host application (i.e., Oolite), which Oolite doesn’t currently do. I haven’t been able to find a tool to generate object-space normal maps that will work under OS X or Windows under Virtual PC, so I haven’t been able to provide a sample.
