Here is the the second high viscosity chocolate render. The first (vimeo.com/48628635) has evident mesh problems.. The main differences between both, is the kind of mesh. While the first one, was done with standard mesh, in the second, i used RenderKit . i also increase the steps value in filter. Vibration problems still exist, almost imperceptible. I'll try to reduce it by increasing the surface tension and the smooth value.
I'm afraid of HD rendre, which can show this small problem, bigger.
(i would appreciate ignore my grammar, jaja)
