Pustules

With the pustules that grow I used approximately 20 blend shapes which all interacted to grow each pustule at the appropriate time. 

These will be accompanied by a sound which makes it seems like ripples in water or drops of water hitting something. This is because they grow from one central object, like ripples.

This is the material I used for the pustules. I wanted it to be the same as the cracking ground which I used for the previous material so I simply added a pinker colouring over the top which seems softer and made the cracks smaller so they still give a texture, but one that is less dramatic.

I also made this texture shinier to show that it is soft and almost gooey.
