-From previous labs you should already have a ''Models'' folder inside the folder where you keep your application executables. To continue to organize your resources properly, you should now create another folder to hold your custom materials. Call this folder ''Materials'' and put it next to your models folder. In order for your Ogre applications to find the contents of these two folders make sure the following lines are in your ''resources_d.cfg'': <code>

       - **Create a member function** that assigns a camera to the render texture and initializes it. This function must accept a ''Ogre::Camera*'' to indicate what camera to draw and ''Ogre::RenderWindow*'' to get the window size. Notice the name "RttTex", this is the name we will use to address the texture in the material script. Call this function in the startup function after you create the camera. <code cpp>void MyApplication::createRenderTarget(Ogre::Camera* camera, Ogre::RenderWindow* window) {
