We were shooting glass cup for client, and I thought this should be done in 3D, not photography. In real world you have no control of the glass IOR, lighting is problem, reflections are problem. Not to mention coffee itself, where the froth is disappearing, and needs to have specific look. My attempt is far from perfect, but I think it works fine. Froth is made using texture from pixabay.com. I would like to know, if there is way of generate it inside blender. Either via particle system, or procedural texture.
Yeah, that makes sense :) Thank you :)
it might get better response to your question, if you post this in community forum... there pictures can be posted and files exchanged... :D
