| - Make sure you can export the model into Panda 3D. You do that by engaging the **Chicken Exporter** script from the **Scripts Window**. When you start Blender, the main screen is split into two windows, a 3D view on top and a panel of buttons below. You can change the contents of each of these windows by clicking on the little icon to the far left in the windows. You'll then get a menu of possible window types (see screenshot). Change the lower window into a **Scripts Window** using this menu. Now in the Scripts Window, select the **Scripts -> Export -> Chicken R56(.egg)...** menu item. In the 3D Window, select the model (it should be outlined in pink to show that it is selected) and in the Scripts Window, make sure the export file path is your working directory and press the **Export** button (notice that you can toggle the **pview** button in the exporter to get a Panda 3D preview after export has finished - in the preview, press **L** to turn on the preview light).\\ | - Make sure you can export the model into Panda 3D.

| - To export the wave to Panda 3D, first double-check that your wave plays when you press the play button in the Timeline Window. Then select the Alien model (in Object Mode) and engage the **Chicken Exporter** script, just like you did in step 1 above. This time you should see new buttons under the heading "Animations:". Your "Wave" animation started at time 1 and ended at time 9. Enter these numbers into the **start:** and **end:** boxes, and put the name "wave" into the **name:** box. Toggle the **pview** button **on** and hit **Export**. You should see a preview with your Alien waving in it. | - To export the wave to Panda 3D, first double-check that your wave plays when you press the play button in the Timeline Window.

| - Look in your working directory: You should have "alien.egg" and "alien-wave.egg". Open **showalien.py** and instead of just loading the model, also load the wave animation and loop it (just need to uncomment the right lines in the code). | - Look in your working directory: You should have "alien.egg" and "alien-wave.egg".
