So I tried making a cup of coffee, the liquid still looks like tea but I'll mess around with settings to make it look like one (of course, tips would be really helpful). But I'm more concerned on how could I make foam for the top layer (white foam) look bubbly and not smooth?

  • $\begingroup$ yeah I've watched this video, but he used to explain less back then and I got lost on how he did some actions, especially when his Blender version differs from mine. $\endgroup$ – lucutes Mar 30 '20 at 18:17

i assume you are using Blender-Guru's doughnut tutorial. While there are more than one way to do this, easiest would be for you to re-trace the steps that you took to create particles for the sprinkles. if not it could be found here.

  1. Create a single sphere bubble, assign a transparent but a little whitish material.
  2. Select the Coffee mesh & Add a particle system to it: type "Hair".
  3. Select the Bubble sphere as the object instead of the sprinkle as shown in the video.
  4. Weight-Paint mostly around the edge where coffee meets glass on the surface.
  5. Play around with random scale particle setting to get the desired effect.

  • $\begingroup$ Yeah this is his tutorial I'm doing. Anyways, I got the bubbles around the foam now, but how do I subtract those areas with the bubbles? It looks now like it grew fungus balls. $\endgroup$ – lucutes Mar 29 '20 at 15:15

  • $\begingroup$ There are few more steps to get a decent outcome. $\endgroup$ – Sadern Alwis Mar 29 '20 at 16:15
  • $\begingroup$ 1. select only the "Faces" in the coffee surface , in the edit mode-> create duplicate Shift+D -> re-parent with 'P' -> this will create a new surface for the bubbles particles alone. so it wont go all over the cup. 2. Try using the Boolean modifier on the Bubble/Bubble particle Surface (whichever that works) youtube.com/watch?v=ViGTkjW997E (reverse this tutorial for cheese) $\endgroup$ – Sadern Alwis Mar 29 '20 at 16:22
