I made this render on Blender 2.8 with Eevee.
The model was made for Mc Donalds commercials I did some years ago.
Eevee is a really interesting render engine, not as good as Cycles but it can give really great results as you can see on this picture.
I made it in 4K and it took less than a minute to calculate.
You can see the process on this tutorial I made (in French).
