Saturn Ring Halo - Spinning, Swaying, Grabbable Head Accessory with Dust Particles | Modular Avatar, PhysBone

[Design] Halo <Saturn Ring> (Saturn Ring 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. A metallic ring reminiscent of Saturn's rings, with fine rock dust drifting around it.

Features

- The ring itself slowly rotates (about 8 seconds per turn). Turning off "Motion" in the Action Menu stops it.

- 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.

- Fine dust drifts from the ring's gap, and larger rock particles drift from the whole ring (can be turned off from the Action Menu).

- Single color only (this product has no color-change feature).
