I would like to be able to import and export .obj files. This is a very simple format and I use it to create my own stuff or to exchange data with Povray. A number of tools, e.g. UVMapper exist that work with obj files. Many free objects are available.
You can use OBJIO, a python script that imports and exports the OBJ-format very well. Get it here: [url]home.bip.net/millfield/OBJIO.zip[/url]
The script works well in Blender 2.23. It presumably does not work with 2.25.
NB: I didn't write this script, I've just mirrored it 'cuz I couldn't find the original url... Good luck!
While Python IO scripts do work, IMNSHO it would be to everyone's advantage if this feature was added to the main program.
