 You need to do the following to set up the right tools:
-  * Download and install the [[http://www.blender.org/|Blender 3D]] modeling and rendering environment, use the latest version
+  * Download and install the [[http://www.blender.org/|Blender 3D]] modeling and rendering environment, use the latest version (2.65)
-  * Install the [[http://code.google.com/p/blender2ogre/|Blender2Ogre]] Plug-in for Blender 2.5 and above
+  * Install the [[http://code.google.com/p/blender2ogre/|Blender2Ogre]] Plug-in for Blender 2.65 and above

     * Run Blender and from **File->User Preferences...** choose the **Addons** panel and click the **Install Add-On** button. Navigate to and select your downloaded ZIP archive.
     * Once Blender has processed the ZIP file you should see the exporter listed, but grayed out. Check the check-box next to it to activate it.

   - **Create a 3D Model in Blender** If you are completely new to Blender, then you can even just use the default cube you get when you start up the Blender environment. However, you should try to modify the cube a little bit if you can. There are a lot of good resources on Blender modeling, including the [[http://www.blender.org/education-help/tutorials/getting-started/|Official Getting Started]] tutorials out on the Internet.
     * It is a good idea to save your model in the Blender file format early and often
-    * Pay attention to what you name your geometry, this becomes the name of the exported mesh (Press ''n'' on the keyboard inside Blender to open the naming panel for the selected object).
+    * Pay attention to what you name your geometry, this becomes the name of the exported mesh. You can browse your object hierarchy in the upper right corner of the Blender screen. Right-click on the cube mesh node and select **Rename** to give the mesh a different name.
   - **Export and Convert Model** Export the model using the Blender2Ogre exporter and save it in your application's **Models** folder. Make sure that any texture imported, baked or generated is saved as a file in the same folder. Run the **OgreXMLConverter** command line tool on the exported **XML** mesh file to turn it into a binary Ogre **mesh** file
   - **Create a New Entity** In your ''createScene'' method in your application, you should now create a new Entity that gets associated with the model resource you just created. Make sure that your code makes this new Entity visible in the scene by attaching it to the scene graph.
-    * In C++ it would look like this:

+Ogre::SceneNode* cubeNode = _sceneManager->getRootSceneNode()->createChildSceneNode();

Try changing values inside it and observe the changes in your Ogre application, but remember to run the OgreXMLConverter again!

   - **Play with Material File** Notice that inside the **XML** file the submesh refers to a **Material** by name, find the corresponding ** *.material ** file in your model folder (it got exported along with the mesh XML file) and read through it. This is the material that Ogre reads in along with the mesh. Try changing values of the material (e.g. the diffuse values) inside the exported material file and observe the changes in your Ogre application (you do not have to run the OgreXMLConverter again for this, the material is already in the right format)
-  - **Create more Entities** Create more entities from the same mesh, but assign different materials to them. Note that you can still use the ''_sceneManager->createEntity("MyCube2", "MyCubeMesh.mesh");'' method. The resource manager is clever enough not to load the model twice from disk. Create a new material inside the same material file you looked at earlier, by copy-pasting the material definition within the same file and changing its name (e.g. into **BlueMaterial**) and give it different values (e.g. making the diffuse color blue). Aassign the new material to a new entity in your Ogre application with the **setMaterialName** method like this:
