Grae has wings, and they're somewhat unconventional. His are constructed from separate strands rather than being two solid entities.
To build the wings, we have two options available to us:
The first option would produce a better-looking result but would require plenty of polygons. In addition, we would need lots of joints in order to animate the wings; each strand would need at least 10 joints to animate successfully. Another plus is that we would need very little texture space.
What about the second option? Both wings could be created with under 60 polygons, and animation would require only a few joints. The downside: We would need more texture space for these wings. Let's go with this safer second option and see how the wings turn out.
Although the wings are not conventional, we still want them to animate like normal wings. That is, we want them to fan in and out as well as flap up and down. With this in mind, we will try and create the basic geometry of the wing by placing edges where the joints occur in a bat wing.
Now, as you did with Kila, rotate around the entire model of Grae, making sure he is perfect before you proceed to optimization.
As shown in Figure 7.49 the Grae model is now complete. Clean up the geometry and the scene, and save your work as Grae_Details.mb.
