Blogpost 4: Week 1 - Exercise 2B - Cluster and Blend Shape Deformers

For this exercise, I'm tasked to create an expression with the knowledge of Cluster and Blend Shape Deformers learnt from the previous exercise. I decided to create a sad face, which is something that I've not tried since the start of the lessons. I searched online for a few visual references to look at the facial movements when someone slowly turns sad. Looking through the results, I noticed that the face slowly becomes long whenever someone becomes sad. Their mouth slowly moves to an upside down U, cheeks moving downwards together with the edges of the eyebrows. There's a small little frown too at the center of the forehead, which shows unhappiness in a person's facial expression.

The four different emotions, including sadness

Using the same concept and methods as the last exercise, I selected parts of the vertices to move them after creating a cluster deformer for them. Using the Blend Shape to control the amount of changes to the original face to show sadness after. The result of the exercise is shown in the video below.
