Summary
In this chapter, we learned how to correctly export our Robot Drone from Blender and import it into UE. We learned what IK is. We also built a basic FK rig for the body controls and then set up IK controls for our Robot Drone arms on the same Animation Rig.
If you can set up basic FK and IK on an Animation Rig, you're well equipped to set up almost any basic character rig and can achieve a lot. Rigging can be very complicated on complex rigs, but these two basic building blocks of basic FK and IK setups are at the core of it all.
In the next chapter, we will do some animation on these Animation Rigs we created.
