This was an interesting project, there was an issue with the conventional photography as it could not capture the ideal look of the chocolate. Since, its close to impossible to get the perfect shape and texture for it while making chocolate.
Solution was to create a 3d model and render of it using 3d technology and create some fun and interesting looking CGIs of the actual product which is the chocolate bar.
First of all basic shape of the chocolate was made in 3ds Max, further some references were gathered to take a closer look at some good looking textures of the chocolate. After that, details were sculpted in Zbrush and then model was brought to Substance Painter to put some textures on. Finally, image was opened up in photoshop and final touches were made and chocolate stream effect was created.
