I made this model for my youtube video about the subject "Nanomesh". It is a object scattering feature in ZBrush and its very useful. With just few steps you can scatter any object on your model. In this example I have scattered those orange pieces on to the octopus arms.
I have used the reference of Character Hank In Pixar Movie Finding Dory to create this octopus Model.
