You could dig through the WMB documentation and write an extractor:
http://www.conitec.net/beta/prog_mdlhmp.htmIf you already have the lightmaps extracted you could use ent_buffers on level_ent and read mesh information from blocks (in particular DirectX vertices with 2 UV sets). Or maybe even try ent_getmesh on level_ent, not sure if that works.
You can then save the directX mesh as a file, or write your own OBJ exporter (the most simple model format).
However... it's probably the better idea to just learn lighting in another program, I bet Blender can do that just as fine/ much better.
