     * 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. 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 (The OgreXmlConverter should be in your path)

   - **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: <code cpp>

+===== Bonus Points =====
+<box 100% green>
+  - **Add a new color to Sinbad**. In the zip file ''Sinbad.zip'' in the folder ''"../OgreSDK/media/pakcs/"''. There are various files that are related to mr. Sinbad. Including a Material file, some textures and extra mesh for Sinbads swords.
+    - **Sinbad has 7 "submeshes"** that can be accessed like so ''_SinbadEnt->getSubEntity( number here )''
+    - **The list of submeshes are:** <code>0 -> Eyes.
+-> Green Skin.
+-> Jewelry, cuffs, belt buckle.
+-> Teeth.
+-> Sword Sheaths.
+-> Accessory spikes.
+-> Boots, Pants, hat, accessories color.</code>
+    - **Now change the material of a submesh.**
+      - Create a file ''MyMaterial.material'' and save it in a folder ''Materials'' next to the Model folder.
+      - Add the line ''FileSystem=Materials'' to the ''resources_d.cfg''
+      - paste this material script into the file ''MyMaterial.material'' <code>material Sinbad/Body2
+{
+    receive_shadows on
+    technique
+    {
+        pass
+        {
+            ambient 0.75 0.75 0.75
+            diffuse 1 1 1 1
+            texture_unit
+            {
+                texture my_sinbad_body.png
+            }
+        }
+    }
+}</code>
+    - **Copy {{:public:t-gede-14-1:my_sinbad_body.png?linkonly| this_image }} into the folder** ''Models'' And now finally apply this mesh to the body of Sinbad, you can tweak the texture if that's your fancy :) <code cpp>// In the MyApplication::createScene function
+_SinbadEnt->getSubEntity(1)->setMaterialName("Sinbad/Body2");</code>
+  - **Add additional entities into the scene** As you could have noticed in the ''Sinbad.zip'' pack file, there was also a mesh for his sword ''sword.mesh''.
+    - **Add a couple of swords to the sheaths on Sinbads back.**
+    - Create an ''Entity*'' for each sword using the ''sword.mesh'' as a mesh file.
+    - **Now you need to attach the swords to the sheath.** Each sheath has a "bone" that is an anchor point to attach the swords. This can be done using the function: <code cpp>Ogre::Entity::attachObjectToBone(std::string boneName, Ogre::Entity* object);
+// Usage would be like
+_sinbadEnt->attachObjectToBone("OhMyBone", mySword);</code>//(**Briefly about bones:** Bones are the logical structure of an animatable 3D object, bones are points of a skeleton that you can move, and assigned vertices will be transformed with the bones thus giving the illusion that the model has joints and movable limbs that follow a skeleton. Objects can be attached to those bones and they will be inserted to that bones transformation space.)//
+    - **A list of bones on the Sinbad model** can be accessed very similarly as the Animation states:<code cpp>// Create a bone iterator.
+Ogre::Skeleton::BoneIterator biter = _Sinbad->sinbadEnt->getSkeleton()->getBoneIterator();
+// Iterate over the available bones and write their names to the console.
+while (biter.hasMoreElements()) {
+	Ogre::Bone *bone = biter.getNext();
+	std::cout << bone->getName() << std::endl;
+}</code>
+  - **With the click of a button or some event; equip the swords to his hands.** The bones of Sinbads hands are labeled Handle in the list of bones. Even though Sinbad has animation for drawing the swords, implementing that will not be required to get this bonus point. Though implementing that Sinbad clasps his hands around the hilts is easy to do using the animations ''HandsRelaxed and HandsClosed''\\  //**Note:** Enabling one and disabling the other is enough for the animation, adding time to them has no effect at all.//
