Fallen Halo Horns — Halo to Horns Transform for VRChat

A cracked halo that falls, splits in two and takes root as a pair of crescent horns — and rises back into a halo when you want.

▶ VRChat accessory · needs Modular Avatar (free, from VCC) · no lilToon needed · drag-and-drop prefab · PC

Two tall horns of black glass, cut into flat facets and broken by glowing cracks, each held in a slim metal collar, with small shards of the old halo circling them.

HALO ⇄ HORNS (one menu toggle, 2.4 s each way)
Turn on "Halo" and the horns pull out of the head, lie down and close into a halo of pale glass above you. Turn it off and it plays the fall:
1. The cracks flare and the halo stops swaying with a shudder
2. It splits in two, front and back, and each half drops onto your head
3. Where it lands a collar rises out of the head and grips it, and the half swings upright into a horn
4. The black runs up from the root to the tip, and the shards break off into orbit
Nothing jumps: every step moves.

ALWAYS MOVING (no menu, shader time)
• As horns: the light in the cracks breathes from the root to the tip (every 3.5 s), and two shards circle each horn (once every 7 s), spinning as they go
• As a halo: it sways, tilts and bobs, and dark ink seeps into its cracks and draws back (every 9 s)
No extra parameters and no particle systems for any of it.

THE MENU (Expressions menu "Fallen Halo Horns" · all remembered)
• Horns: on / off. They gather from shards (1.2 s) and break apart (1 s), never a jump
• Halo: horns ⇄ halo (2.4 s)
• Colour: Crimson Fall / Violet Abyss / Ashen Grace. The colours cross over in 0.9 s while a band of light runs from the root to the tip
• Glow: a radial for the light in the cracks
• Size: a radial, 0.5x to 1.3x (starts at 1x), to fit your avatar's head

3 COLOURS (all in one prefab, switched from the menu)
• Crimson Fall: black glass, red cracks, gold collars
• Violet Abyss: dark violet glass, violet cracks, silver collars
• Ashen Grace: pale ash glass blackened from the root, gold cracks, gold collars

SIZES (measured in Unity, at 1x)
• Horns: 25.6 cm tall, 25.2 cm across the pair, 4.8 cm at the root
• Halo: 27 cm across, 9.4 cm above the roots

HOW IT SITS
It follows the Head bone (Modular Avatar Bone Proxy). The prefab is placed for an average head; move the "Horns" object or turn the Size dial if your avatar's head is bigger or smaller.

WHAT YOU GET
• FH_1.0.0.unitypackage: 1 prefab, 1 shader made for these horns, 1 material, menu, animator (no textures)
• README in English and Japanese

PERFORMANCE (this item alone, measured in Unity)
• 2,092 triangles · 1 mesh · 1 material · no textures · no PhysBones · no particle systems · no lights
• Synced: 5 parameters, 26 bits
• VRChat SDK performance rank: PC Excellent

GOOD TO KNOW
• PC only: it uses its own shader, and Quest avatars can't use custom shaders.
• Needs Modular Avatar (free, from the VRChat Creator Companion). No lilToon needed.
• Needs a humanoid avatar (a Head bone).
• The glow looks best in worlds with bloom.

AI DISCLOSURE (AI-Assisted)
The code that builds these horns (mesh, shader, Unity setup and animations) and the text on this page were written with help from an AI assistant. An AI image generator made rough concept sketches I looked at while designing; nothing it made is in the files or in the preview images, which are rendered in Unity from the actual prefab.
