I am at beginner level. One of the projects I am doing is to create a glass with fluid. Like a glass of water or a glass of wine. Now I can find quite some tutorials on how to create the glass but very few if none on how to create the fluid (with a realistic result). So I am searching for tutorials (cycles based). I did some googling but did not find much. Or is this a subject for advanced Blender artists ? Oh ...and I am not looking for the water /wine flowing into the glass but just something like this
