Hello - I have come across this OBJ export script from sourceforge:

http://sourceforge.net/projects/blenderobjex/

It does not work with Blender 2.26 for Windows. Can somebody get this to work with Blender 2.26 on Windows? I dont understand Python or scripting. What im after is to be able to export mesh, texture, and material data, and this script is supposed to do that. - Thank you.

Here is the contents of the script:

Hi,

the Blender210 and GUI modules are not included in Blender 2.26. You'll have to use prior versions of Blender for that.

both modules will probably never return . The fileselector from the GUI module will probably return in some other form.

With regards,
Michel

What are "GUI modules", and how can this script be modified to be used wint Blender 2.26? What is "fileselector from the GUI module"? Is it possible to put back into Blender 2.26 "GUI modules"?

Graphical User Interface
they do things like buttons, and textinputs.

I would look for what values the necescary ui items return, and set them to hard coded values, as a hack.
but I know python
(I could suggest how to change the script if you put it into code block when you posted so that the indentation would be saved[code]...[removme/code])

it is a lot like the open and save windows
----------------------edit----------------------
I now see a link to the sourceforge page
am too lazy to extact a tar.gz to try to update it
why not use an older version of blender? 2.23 should work.

Thanks for you reply z3r0_d, but your talking way over my head. I dont konw the first thing about programming, scripting, file extensions, GUI modules or anything related. All i know to do is make pictures, and shapes. What im after here is to be able to take a shape i made in Blender (with UV textures added) and export it to be used elsewhere.

I am (again) too lazy to fix it, but I would suggest you try it in Blender 2.23, not 2.25 or 2.26.
