Sorry...plainly forgot...
Well, Im sure these arent the latest....as I remember testing ones that actually worked as a windows app (with shift click) ...that referring to mim tools...and to oct tools (Blender's way

) ...probably the python script for Blender...yet needed the mesh to be a single mesh, not made of several objects...but can't say...I'm not very much on free tools and these things lately...
The mim tools advantage is that uses OBJ format, so any free or not free tool would do. I have done lightmapped levels with these tools, and checked my levels with the simpleviewer he made, quite nicely. It was a dos batch file, quite easy to use. Just u need a bit to read the doc.
The oct tools...may be more deep, as u need to know Blender, to know to use/install its plugins, and...to use well FSRAD (he also made a version running under wine working, but probaly is not in this zip...)
But I also got it to work. And the viewer showing both rt opengl lights done in Blender, as well as the whole way of going to fsrad and displaying later on the OCT file. He made also an oct loader, and mim loader for Irrlicht, and both are in this zip.
ABout the use of all of it, remember well to read the doc, and remember that FSRAD has a hige button of help somewhere on its interface...so, to go the Blender route, (just in case you can't lightmap with other thing, but if I remember well, you can use also fsrad with MIM tools and OBJ format) read that help too.

there it is the 5 MB zip, but just remmeber: it'll stay only 14 days since the date of this post...rules of an already generous free file hosting....
BTW, I haven't known about Murphy dunno how's him...perhaps he couldn't get an inet connection(was having probs even to get a machine to code) there where he lives now, and so, abandoned the development of this....
