A bit different, decided to tackle Coffee foam, tried first a Cycles foam shadder but it was utter rubbish.
Watched a few of Dravia/Sharlylbg tutorials on SSS and decided to combine a few materials and try for the fisrt time custom bumps and displacement maps.

Still a WIP, but feel like already leaned so much with it.After several attempts decided to use PS High map from base Diffuse to create a rough displacement that I use with MultiRES modifier on high settings (7) and real displacement modifier that I could use sculpt to modify the bigger bubbles and then use Cycles to bake better displacement maps.

Still have a dew things to tweak and some others to add like coffee beans but overall quite happy how foam turned out.

The foam looks real, very nice photorealistic result of the whole coffee cup!

Tks, its funny because I saw a lot of videos on people explaining weird methods to make displacement maps , ranging from getting heights with fancy methods to using plug-ins when in reality, turns out its a lot easier than I expected:

Very short video and exactly to the point:

Ended up using a rough height map from difuse coupled with displacement modifier to get a rough shape and Because of MultiRES modifier enables to enter directly in sculpt mode, tweak it a bit and render displacement map.Fast and easy.

Its not finished thought.
