Hi all,

I was wondering whether anyone recently made Brad work using any kind of Linux?

I have installed the script into /opt/brad, added the symlink to my ~/.blender/scripts, and set the brad_path in brad.py. However, it seams that the script cannot load its libraries, and I am a real python noob, so anyone understanding this?

(...)

Which version of Python are you on? It should be something in the low 2.x
range (I think it was written for 2.3). 3.x will most likely cause problems.

As the error message states, see PEP 263:
   http://www.python.org/dev/peps/pep-0263/

The encoding declaration specified there needs to go into the
file(s) failing to load.
Figuring out the actual encoding will be another challenge.
The value \xe8 may appear in several encodings.

Lars, the code is an e-accent-grave in the ISO 8859-1 character set. Current versions of Python can be made to accept that character set by adding a comment containing "coding=latin-1" in the first two lines of the module file.

This could be one of the following lines:
  # coding=latin-1
  # -*- coding: latin-1 -*- (for Emacs)
  # vim: set fileencoding=latin-1 : (for vim)

Hope this helps!

Francesco, if you're reading, could you pick up this change?

Hi!

I hope I do not bother folks not interested in Blender, as this is a rather specific problem of a tool developed for supporting Radiance, not a problem related to Radiance itself.

Which version of Python are you on? It should be something in the low
2.x range (I think it was written for 2.3). 3.x will most likely cause
problems.

Thomas, I am using python 2.7.1 coming with my current Ubuntu, and tried various 2.4-2.5 releases of Blender.

Randolph, Georg, I added a line reading

# coding=latin-1

to the beginning of the file.

Still, I get a "mismatch in assignment". The full output of the Blender 2.49 session is:

Buffers are used when communicating between Python code and
extensions written in C. That probable means you are seeing a bug
in some Python code, which is using the Blender API incorrectly.
That bug could be in a file coming with Blender (eg. BaseWindowClass.py)
or in a file coming with brad. Hard to tell without a detailed
analysis of the interaction between the two.

It is also possible that the added coding specification resulted in
some API function receiving an Unicode string now instead of a byte
array (traditional text string).

In either case, the author of brad would be in the best position to
identify and fix the problem.

The Blender API has been updated, and brad has not been updated to follow the changes. I can't even find the packages brad uses in the current Blender API docs.

I really don't have time to work on this more, unfortunately--anyone else who knows Python and OpenGL want to give it a try?

I can look at it if it kann wait until the weekend. But I don't think there
is much point in updating the whole package to a new Blender version. The
current Blender API is still not finalised and may not offer all the
features the script needs.

The best way to use brad is to use an old version of Blender.

There is a new project that works with Blender 2.57:

http://www.ods-engineering.com/blendme

Don't know if it's already released yet, though.

That looks cool, but they seam not to fully release it as open source, which leaves some questionmarks (it is basically a great integration of existing open source software into Blender).

Cheers, Lars.
