Blender: Section 4

 Here is the low poly fish model, with armature attached and set to be rigged. 

Here's a sneak peak into weight paintings, which is slow but fun to figure out.

Here is where shape keys came into play, with the mouth being animated to open and close slightly.

This is the keyframe section, where he had us make four key frames by animating the fish. I don't understand the point of auto-keyframe, and I wonder why use it when he says to just use A + I.
