Gargantua (Shaders & Geo Nodes) - Blender
Interstellar is still one of my favorite movies, and it is re-releasing this year :) So why not make Gargantua as a tribute!
I wanted to re-do my previous attempt at making a Black Hole in Blender, after many years. I remember making one in 2021 when I was fairly new and naive to procedural content. Having gained the knowledge and familiarity, I took on the task to make something that would look good, and be somewhat accurate? The results turned out pretty good, and the method is pretty simple, depending on your familiarity with nodes. Don't forget to increase the number of transparent passes in the render settings, because it can cause artefacts.
This blackhole has been made using Geometry Nodes and Shader Editor in Blender.
Another angle for the blackhole. It's not even close Nolan's genius :)
The shader graph for my accretion disk. This was the main part, which gave the volume to the black hole!
For the blackhole, the IOR changes from outside (maximum) to the center (minimum), giving it that "black-hole" look and warping the light around itself.
The final composite. For post processing, I mainly used Glare, and Chromatic Aberration and basic Color Correction.
