How would i go about creating a foam coffee like this?
I’m also curious! I did find this YouTube video with awesome looking foam: Realistic Animated Foam Material - 3D Asset Overview & Tutorial - YouTube
It’s not that expensive and based on animated displacement maps but I’m on a mobile connection and while I’ve unlimited data I need to send a text message every 2 GB and think the pack is around 70-80GB. Might buy it once I’ve also time to sent a text every minute or 2 
Not sure if it’s useful for you, since they use displacement maps it will need a lot of memory on the GPU (if you render at GPU).
That looks amazing, but my PC can’t handle that, i even found an easier way that my PC also can’t handle. It’s all with keyshot https://forum.keyshot.com/index.php?topic=28239.msg118253#msg118253
He also has a youtube tutorial https://www.youtube.com/watch?v=-bYX3K0izn0&t=315s

Wow! That bathroom stuff with foam looks awesome! Gonna try if I get something like that, Google translate for the Chinese parts
And never quit 3D, just focus more on things like modelling or so, great skill to have I think. And I’m sure there are people around that can help you render if needed.
I just noticed the lazy background curve haha
6.5 hours render 
does anyone know how to add a texture map to the diffuse of the scatter medium?
Next time i will try using translucent material it might be faster

Well it certainly goes in the right direction, nice! It’s a shame that the reflections in the glass are distracting from the nice foam you fixed.
I don’t think the scatter medium has a diffuse map. Don’t know what you like to do but maybe you can just get the effect by adding another label so you can f.e. colour the albedo of the scattered medium?
thanks, i don’t know what’s causing the reflections, it could be frrom the envirenent or ior value, they are not noise or geometry issue.
Sorry for resurrecting this one but the best result you will get is if you comp it in Photoshop. For the top cap like part use some texture with combination of a brush and do it in perspective. Then apply some warping deformation. For the side thick part use some texture and apply it on a custom displacement map to get the curvature of the glass so it can sit right on top of the fluid. Final step would be to relight it properly using a pen tool or a brush tool extract edges and mimic overall lighting from Keyshot. If you are good at PS that alone will not take more than two hours and you will get a controlled result instead of random result in Keyshot material tweaking and searching over and over again.
Hi everyone! So glad I stumbled onto this thread - I hope I can add something to the workflow here.
The way I approach foam in KeyShot - you truly have to separate the geometry. So you’re dealing with the coffee / foam independently. And ideally - a transitional piece of geometry between the two. You want as much control as possible for something like this!
I’ve included a link to a scene with a VERY rudimentary beer / glass model that has the “Foam” section separated. Let me know what you think!
