A complete black hole built for production work: accretion disc, photon ring, gravitationally lensed arcs and relativistic polar jets. Eight colourways are included and every one of them works outside Blender.

Most black hole assets are one render engine's shader graph, which is why their FBX and OBJ downloads arrive as bare mesh with nothing on them. This model has no procedural nodes anywhere. Every glowing surface is real geometry carrying a baked emissive texture with its own alpha channel, so it renders correctly in Unreal Engine, Unity, Godot, three.js, Marmoset, Maya, 3ds Max and Cinema 4D exactly as it does in Blender. It was test loaded into a plain WebGL viewer with no lights and no post processing to verify this before publishing.

The model is rotationally symmetric about its spin axis, so it holds up from any camera angle rather than from a single hero shot. Relativistic Doppler beaming is baked into the disc, so the approaching limb runs brighter and bluer while the receding limb goes dimmer and redder. The disc carries logarithmic spiral filaments, a puffed hot inner region tapering to a thin outer rim, and a blazing inner edge at the innermost stable orbit.

TECHNICAL SPECIFICATION31680 triangles16669 mesh vertices in the source file. Exporters report 17111 in the GLB because UV seams split shared vertices. Both numbers describe the same mesh.7 separate named objects under a single parent emptyQuad mesh throughout apart from the triangle fans at the poles of the event horizon sphere. No n-gons.Real world metric scale. Event horizon radius 1000 mm. Disc 13 m across.Overall bounds 18000 x 18000 x 16400 mm including the jets.Pivot at the world origin at the centre of the hole.Z up in the Blender file. Y up in glTF and USD.Animated. 240 frames at 24 fps. Seamless loop with differential rotation so inner structures orbit faster than outer ones.No rigging. No lights or cameras in the exported files.

MATERIALS AND TEXTURES6 materials applied at any one time. 41 ship inside the .blend so all eight colourways are ready to select with no re-import.PNG RGBA throughout with opacity carried in the alpha channel.Accretion disc 2048 x 512. Outer haze 1024 x 256. Lens arc 1024 x 256. Jets 512 x 512.Star dome 4096 x 2048 equirectangular, usable as a skybox or world background in any engine.UVs are non overlapping with one UV set per mesh. Every mesh is unwrapped.

COLOURWAYSGargantua Amber. Cygnus Blue. Nebula Violet. Emerald Jade. Inferno Crimson. Platinum Ice. Voltaic Duotone. Prism Spectrum.Each colourway also ships as its own GLB and FBX with its own texture set.

ENGINE NOTESImport at 1.0 scale for metres. The materials are emissive so the model lights itself and needs no lamps in your scene.For the look in the preview images enable Bloom on your post process volume. The Blender file already has a Fog Glow and Bloom chain in its compositor. Without any bloom the model is still correct, just crisper.The jets are separate objects. Delete them for a quiet hole.Gravitational lensing is view dependent by nature, so the lensed arc sits under an empty called BH_LensAlign. Rotate it about Z to face your camera, or add a Track To constraint for a fly around. Hide the arc entirely and you still have a complete physically shaped disc that reads from every angle.
