I was thinking about small errors. Which it IS possible to correct using the paint mode in gile[s]. But it needs to be imporved to be a 'good' solution, I agree on that :)
Here's a shot of the lightmap viewer, so you can see how it packs the maps. The lightmap has been blurred, so it's a little fuzzy around the edges :)
[edit]One thing to note on that screen is that each section of the building (each arch) is a seperate model, but when packing the lightmap gile[s] performs a continuity check on all models, and groups similarily angled and continuous polygons together. This minimizes the space needed for each polygon, and reduces render errors.
