I'm trying to write a lightmap creation tool for my engine and i'm searching for references... does someone have a link to a tutorial or an article?

i foud that making own lightmapper is not for me and i advice you to use a ready one. you may use programs for lightmap generation:
Lightmap maker(free, but its only v0.3) http://www.windssoft.com/
gile[s] (i use this, cheap and very good program) : http://www.frecle.net/giles/

or Fluid Studios FSRad : www.fluidstudios.com

and some more, but these are great and i think will save lots of your time.

here is the spec of its own format(gls): http://www.frecle.net/giles/glsspecs.htm you may use it.
i do not export my models directly from gile[s]. i export the model to 3ds or x with lightmap texture coordinates then mix it with orginal texture coordinates with my converter because i use my own format for lightmapped meshes.
i remember there were scripts about how to export and import obj files with the program. you may write your own exporter, but i dont advice, try to make a converter that takes 2 models(orginal and lightmapped) and converts to your format. i use that system.
hope helps.

You will quickly find out that getting good shadows on a low piece of resolution
crap is harder than it looks. :)
