Blender can export .xml files which can then be converted to .mesh with the Ogre CommandLineTools. I would recommend downloading an older version of Blender (2.49b) which has the correct exporting
and importing scripts installed. For IT it's probably the best version of Blender to use, as I have been told.
You can download Blender 2.49b from here:
http://download.blender.org/release/Blender2.49b/You will need to install Python 2.5 which can be found here:
http://www.oldapps.com/Python.php?old_python=23Lastly you will need the Ogre CommandLineTools version 1.6.0. The download I've provided for this is for Windows, not sure where I can find a download for different operating systems:
http://sourceforge.net/projects/ogre/files/ogre-tools/1.6.0/OgreCommandLineTools_1.6.0.msi/downloadOpen Blender and with your object selected, click File > Export > OGRE MESHES. The exporting menu will show up. You can create the .material name if you have a texture applied and for the material I'm not exactly sure what settings should be applied but this is what mine looks like:
Where it says " Export Meshes Path: " you can choose where you want your meshes to export, choose where your CommandLineTools are installed.
Click Export and go to where your CommandLineTools folder. There should be a .material (if texture was applied) and your mesh which is a .xml format. Drag it into the OgreXmlConverter.exe file and it will convert it to a .mesh. You can now use it in your game.
I hope this helps
EDIT: I would take a look at the KITO forum for some tutorials on item making if you're having exporting problems.
