This tutorial creates an 3D ball of plasma like you might get with fire in zero gravity (zero-g) or if you have a really, really unstable star. And it's based on TextureLabs After Effects fire tutorial. I'd already been looking at improving my Sun tutorial from my Makin' Planets playlist when I realised I could adapt Brady's procedural fire to work as fireball in space.
In this video, I show you how to start with a 3D precomp, then we'll using a few of @VideoCopilot
free tools to link one comp into another. From there, following Texturelabs recipe, I add fractal noise, displacement maps and colorama to create a powerful, dangerously volatile star.
