Bone Halo - Swaying, Grabbable Head Accessory with Particles | Modular Avatar, PhysBone, 5 Colours

[Design] Halo <Bone> (Bone Halo)

An overhead halo (3D accessory) for VRChat. Works with Modular Avatar - just drop it onto your avatar and it will automatically attach above the head. Sharp, bone-like spikes line the entire ring - an ominous yet beautiful design.

Features

- Follows your head with a gentle sway when you move. Drifts slightly even while idle.

- The ring can be pushed when touched, and grabbed to move it further.

- When released, it slowly eases back to its original position.

- White, powder-like particles of light softly drift from the whole ring (can be turned off from the Action Menu).

- Includes all 5 colours (Default, Gold, Silver, Rose, Black).
