Using displacement in my materials is something I’ve experimented with a lot, but not something I use in practice too often – but it’s incredibly useful when your geometry needs to be in sync with a procedural material in a way that normal map manipulation and bump mapping can’t achieve.

This is my take on a bubble material. It’s meant to look soapy, but it looks a lot like the sizzling grease you get when you cook things like bacon. It comes with a lot of customization options, and you can animate it easily by adjusting the vector offset parameters at the bottom of the node group.

There are probably further refinements to be made here, but I find myself getting… intimidated? burned out? bored? with these projects once the node tree gets sufficiently large, so this is how I’m releasing it. 😝

As-is, I think it could be useful for the right project!
