i modeled this in blender a while ago for testing something else. modo isn't that great for things like extruding roads along a curve since it doesn't have something like a construction history or modifier stack yet. you wouldn't be able to go back to edit the curve if some change were needed.
to bake the light map i used modo. blender is supposed to also feature baking now but i haven't figured out yet how to use it properly.
Quote: Vent do you think it would be possible to integrate this into the obj_splitter tool you wrote? Then people could create entire levels in any 3D app that does obj, with lightmaps -- dreamy!
unfortunately obj doesn't support two uv-sets either i think. so you would also have to export twice (a second time with the light map uvs) and i could add a small option to append something like _lm to the model filenames during the second export. then a script could generate all the needed mesh files. it would make the whole thing even "hackier".
