Time for action — decreasing the texture count

By using the previous code we are going to reduce the texture count of our compositor.

1. We need a new compositor, this time with only one texture:

   compositor Compositor5
   {
   technique
   {
   texture scene target_width target_height PF_R8G8B8
   

2. Then fill the texture with the rendered scene:

   target scene
   {
   input previous
   }
   

3. Use this texture as the input texture as well as the output texture:

   target scene
   {
   pass render_quad
   {
   material Ogre3DBeginnersGuide/Comp2
   input 0 scene
   }
   }
   

4. Again, use this texture as input for the final rendering:

   target_output
   {
   input none
   pass render_quad
   {
   material Ogre3DBeginnersGuide/Comp3
   input 0 scene
   }
   }
   

5. Add the missing parenthesis:

   }
   }
   

6. Compile and run the application. The result will be ...
