Here is the original look of the model, with no rigging, just a basic model.
The joints are added in at this point, with the complex hypergraph beside which is good for tracking of the right joints.
The constraints are being added into the Hand Control and thus, enabling the bending of fingers.
Choosing multiple objects with the hypergraph than clicking on the model itself is better as clicking the model would sometimes cause problems such as selecting the skin or the joints instead of the controls.
Here is an end result of all the rigging that has been added into this model, there are more complex ones but are not taught inside the video, but they did said there are possible ways to create them such as facial features.
I have to admit, this is one of the most tedious part about Animation. However, without these being done to a model, movement of the joints and skin will not be possible. There is no other way, other than learning from the basics before I can even create better animations in the future. I still do enjoy as I know I'm taking a step at a time towards being better each time a task is given to me.
