Importance of lightmaps? Although lightmaps are still widely used in many of the most current engines (Unreal Engine 3, Source Engine, etc..), are they still needed? I ask this only because I have a half-written engine which uses dynamic lighting only (very Doom 3...

Can any one help me? If you're making the models yourself, most X file exporters have the option to export to either a binary or non-binary format. From there it's just a matter of reading the file in (probably with DirectX) and parsing it.
