Physically Accurate Black Hole for Blender

From the creator’s description

Beyond Interstellar visuals, now in your viewport. This is not a simple black sphere with a glowing ring. This is a physically accurate representation of a rotating (Kerr) black hole, featuring true gravitational lensing, a redshifted/blueshifted accretion disk, and the elusive photon sphere. Designed for filmmakers, game developers, and space-artists who demand realism where Einstein meets real-time graphics. What Makes It Real? Gravitational Lensing: Light from the accretion disk bends around the event horizon. You don’t just see the front of the disk; you see the far side warped above and below the shadow, exactly as predicted by General Relativity. Relativistic Doppler Effect: The accretion disk is asymmetrical. Matter spinning towards you at relativistic speeds blazes with intense blue/white brightness, while matter receding dims into deep red/orange. Photon Sphere: A razor-thin ring of light trapped in orbit around the shadow, adding that critical cinematic rim light. Volumetric Accretion Disk: High-resolution, swirling dust and gas with realistic density falloff, not just a flat 2D texture. Frame-Dragging (Lense-Thirring Effect): The singularity’s rotation literally twists the fabric of space around it. The inner edge of the accretion disk is dragged along, forced to orbit in the direction of the black hole's spin. This creates a tightly bound, intensely hot "inner ring" distinct from the rest of the disk. The D-Shaped Shadow: Because of extreme frame-dragging, the "shadow" (the photon capture region) is not a perfect circle. It’s flattened on one side, creating the characteristic Kerr "D-shape". Tutorial for those who want to understand the principles: Compatible with Blender 4.2+ (you need Ray Portal BSDF to exist). Created in 5.1. Free version contains a simple (not quite realistic) gravitational lens, but it renders much faster.
