Creating and animating bubbles
Alvaro Moreira breaks down the best methods for making and animating coffee bubbles in his video tutorial series
To help you out, I've included some tutorial assets which can be downloaded from here.
This is a tutorial on how to create coffee bubbles which morph into a logo. First of all we'll create the bubbles using a Birth Texture operator, so we can control the particle's position and size based on a grayscale map. Then, using a black-and-white image of your logo, we'll animate the particles using a Data Test.
Last but not least, I'll show you how to mesh the particles and create a tension between the coffee and bubbles using Frost.
Creating bubbles
In this first part we'll create the bubbles using a Birth Texture operator, so we can control the particle's position and size based on a grayscale map. This grayscale is a procedural map. It's created using a Radial Gradient Ramp and a noise map.
Animating bubbles
With a Data Test and a black-and-white image, we'll keep the desired particles in one event and send the others to another event. Next we'll create some animation in order to make some of them draw, others to pop and the logo ones to stay there wobbling a little bit.
Bubble mesh
The bubbles look better and render faster when they're meshed, so we'll create it using Frost's Union of Sphere's meshing. Then we'll generate a liquid tension between the coffee and the bubbles in order to give that classic liquid deformation.
