In this lesson we'll take a look at the chaotic bubbling of boiling liquid. At first glance it appears to be a heavily complex effect but essentially it's just a large number of simple bubbles.
In the videos, I'll be demonstrating the way a bubble breaks the surface and how to apply that to a scene of simmering, or boiling liquid.

The design will vary depending on the liquid that's boiling. For example, lava, porridge, mud, custard.. all these liquids are very thick and the broken bubbles will have thick, heavy shapes.
In the video below, we look at an opaque and relatively thin liquid.

Just as I mentioned in the design section above, thick liquids have slower, heavier bubbling than ordinary water, which as you've just seen has very fast, chaotic bubbling.
This effect always looks much more complex than it is, and once you start thinking of it as individual bubbles, it's really not that difficult. How you approach it depends on what the scene requires, but it's very easy to turn something like this into a cycle, which will save you lots of work if the bubbling is to appear in more than one scene of varying lengths.
