I found the problem of creating a convincing bubbly chocolate cross section model quite an interesting challenge. I was looking at the existing advertisements for similar products, and could not find many I liked. Many of those were just made in Photoshop, some even by adding coffee froth bubbles, which was just plain silly.
I gave it some thought, and first, I considered simulating particles to randomly fill and get out of bounds of a shape that resembled a cut piece of a chocolate bar. After that I would mesh the particles, and use the mesh to subtract it from the solid body of the chocolate cross section, thus creating naturally looking holes. After some trial and error, I made it work.

This process gave a pretty decent result, after some trial and error. I tried using the bubbles as a insert mutimesh brush, but the results were not satisfactory. Subtracting a complicated multimesh tool from a mesh can be tricky. So, I decided to subtract the bubbles using dynamesh instead...
After that, some convincing grunge was needed on the surface of the cut, and the edges, but also, more variation and uneven holes, in depth, and in size. The new holes were easy, just subtracted some spheres from the mesh, adjusting depth and size along the way. In order to be able to add detail to the surface and edges, I needed to split the mesh into polygroups.
I applied some polishing to the bubbles, and a few layers of noise to the surface in between the bubbles, and the edge respectively. What was left to do was model the wrapper, which was quite an easy one, and then design the graphics and the poster.
After a few fails, and some thinking, finally I decided to go Japanese on the design. I studied Japanese candy wrappers, and gave it a try. The chocolate name literally translates- Baburu, bubbly milk chocolate. Baburu is the Japanese word for bubble. After rendering the chocolate, I created the poster as well, trying to maintain the spirit of the Japanese design.
Hope you enjoy the results!
