: After Effects tutorial: Converting a 2D effect to 3D (using a bit of Maths) to make a Black Hole
Long title, but it about covers it. In this tutorial, I'm demonstrating how to get the look of an Interstellar Movie-type Black Hole using the Bulge effect, 3D layers, adjustment layers and how to use expressions to compensate for the fact you can't use Bulge in 3D space.
I've included the project file here:
