[Brad] Help:Setting up a radiance system--brad

[steve michel]

I've been using brad and generally find it handles the main radiance tasks 
quite well.
But I found three issues: (these don't prevent me from using brad but maybe 
need to be addressed by the programmers)

1/ starting brad generates the following errors at console:

<<Compiled with Python version 2.4.
Checking for installed Python... got it!
brad.py:0: SyntaxWarning: name 'config_path' is assigned to before global 
declaration

2/ Using the sky weather settings and hitting the preview button results in 
a python script error:

<<failed to initialise psyco
Traceback (most recent call last):
 File "/home/family/.blender/scripts/brad.py", line 1150, in mainguibevent
   skyweatherwindow.testSky()

442, in testSky
   self.exportSky(skyfilename, 1)

   skyfile = open(skyfilename, "w+")
IOError: [Errno 2] No such file or directory: 
'/home/family/.blender/scripts/brad/brad/tmp/tmp.sky'>>
--------------------------------------------------------------------------------------------------------------------------------------------


3/ this issue is probably trivial for experienced users: SCALING of lights

If I insert a radiance ies light into a blender scene, how do I check that 
the relative scales of blender objects AND radiance lights coincide????? A 
room 10x 10 units in blender with an inserted light fixture from radiance 
libraries might might too small or too big..does anyone know of this and/or 
can explain???

regards
steve
