Realblackhole 2.0 is a Blender addon that procedurally generates a realistic black hole inside the Cycles engine. The composition brings together a black hole, an accretion disk, and a background, all procedurally generated and open to adjustment. Each element can be animated and managed on its own.
Custom nodes handle the textures across the scene. The addon ships with a guide and a presentation of the tool, and it is distributed under the GPL license. Version 2.0 is a functional addon, following version 1.0, which was an editable .blend file.
Realblackhole 2.0 works with Blender 3.4 and 3.5+, with the listing citing versions 4.0 to 4.5, and it renders through Cycles. A demo video is available for a closer look at the addon.
