 So, you got your rig, but you want to understand and control it easier. And that is exactly why you wanted to learn custom shapes in the next 60 seconds. Alright, let's do this. First, create a new collection by right-clicking here, click New, and name it Custom Bones. Click the eye to turn everything else off for now. And in this collection, press Shift-A to create a mesh of your choice from scratch. Or if you have a 3D shape you've already created, you can import them here. Just make sure that you name them and that they are in the middle of the scene. I'm just going to use a sphere for my knees and a pyramid for my elbows. So, here's how you put them in. Now, turn your armature back on by clicking on the eye, select your armature, go to Pose Mode. Click on the bones you want to change the shape of. Under the Bone tab, go to Viewport Display and Custom Object. Select the name of the object that you want it to look like, and look at that. Now, it looks like your 3D object. If you want to change the size, shape, or angle of this at any time, go back to the object, make your adjustment, and then apply it with Ctrl-A. If you change rotation, apply rotation. If you change size, apply size, and so on. And you're done. Now, it'll be much easier to recognize the difference between our elbow eye caves and our knee eye caves for easy animation.
