Hi everyone,
I've finished the implementation of bump-mapping for the light-map generation. You can see some of the preliminary results here:

(note I've since improved the blending at edges, which is still quite rough in this example)
The speed penalty is minimal, so I'm planning on making this an on-by-default feature in L3DT Professional. I find it to be particularly useful for high-resolution light-maps, as the bump-maps provide nice detail that would otherwise be lacking.
Anyway, this addition requires a small change to the climate files, as each land type now has some settings for bump maps (similar to texture settings). I'll sort all this out over the coming week.
Cheers,
Aaron.
