This week marks the further development of the foam effects for the particles. Since the effects are due on this Wednesday, I need to ensure that I push them as far as they can go.
The technique that I'm using for the foam effects is one that is standard in terms of Houdini effects: foam from fluid advection. It utilizes both Flip and Popnet techniques. On top of this, some further blurring in post in rotoshapes could help increase the drama of the foaming over the chemicals.
