Hi Kirk.

I know Francesco did not have much time to keep b/rad in sync with
Blender development. I expect that the problems with the menu
are the result of a failed "import" of brad. The bundled scripts
are tested with Blender 2.41, brad is not.

I made b/rad work recently with an explicit "brad_path" setting.
I have made a few changes to the original file as well but i don't
think they are important.

As first step try to set "brad_path" to the directory where you
keep the "brad.py" and the "brad" directory, i. e.

brad_path = "/Users/kirk/blender/scripts/"

(around line 101 in brad.py; line count may differ but it is well
commented). That did the trick for me on OS X 10.4.4, Python 2.3.

When your at Python 2.4 I think you know your way around Python
and OS X. Keep an eye on the imports in the script. If they fail
any error message could be the result. Perhaps add

try:
     import ...
     import ...
except ImportError, err:
     print "ERROR", err

to the import section to check this explicitly.

I got my version sometime after September 2005 from Francesco's web
site (tar ball, not CVS).

Me too ;)

You can download the snapshots here:

http://home.arcor.de/tbleicher/blender/bliff/download.html

There is no tutorial and they are not tested much. I have not
yet separated the brad parts from the GUI toolkit so it's one
download. The zip file is fresh and contains today's texture
mapping update.

Don't get frustrated,
