Star Rain Umbrella — Opens, Closes & Rains Stars for VRChat

▶ VRChat avatar accessory · needs Modular Avatar and lilToon (both free, from VCC) · drag-and-drop prefab · Quest prefab included

A night-sky umbrella with gold stars and a little star charm on every rib tip, held in your right hand.
Open it from the menu: the folds swing out, it goes half-open, then the canopy snaps taut and gold star dust starts falling from the rib tips like rain. Close it and the charms fold in with it. The gold stars printed on the canopy twinkle all the time (PC).

THE MENU (Expressions menu "Star Umbrella" · everything remembered)
• Show: on / off
• Open: open / closed (starts open). Opening takes 0.68 s: the folds swing out, it goes half-open, then the canopy snaps taut with a small overshoot and settles. Closing takes 0.6 s (half-open, then folded). The 8 rib-tip charms move with the canopy
• Star Rain: on / off (PC prefab). It starts once the canopy is fully open and stops when you close it
• Colour: Night Navy / Rose Dusk / Moon Silver
• Size: a radial from 0.6x to 1.4x (starts at 1x)

ALWAYS MOVING (no menu · PC)
• The gold stars printed on the canopy twinkle one by one, open or closed (lilToon emission on the PC prefab; the Quest prefab has no glow)

STAR RAIN (PC prefab)
• 1 particle system: falls in 8 streams from the rib tips
• 110 particles a second (each a short trail of tiny gold glints), each lasting 1.8 s, at most 240 at once (197 in the air after 3 s, the lowest about 1.99 m below the canopy edge, measured in Unity)

3 COLOURS (all in one prefab, switched from the menu)
• Night Navy: navy night sky with gold stars
• Rose Dusk: plum running into rose
• Moon Silver: navy running into pale moonlight blue

SIZE
At 1x: open 77.8 cm wide and 95.6 cm long (top star to the end of the handle); closed 15.4 cm wide

• 1 PhysBone (the 8 rib-tip charms, 9 bones)
• 1 constraint (VRC Parent Constraint) · no lights, contacts or parameter drivers
• Synced: PC 19 bits · Quest 18 bits
• VRChat SDK performance rank: PC prefab PC Good (particle system count and particle total Good, everything else Excellent) · Quest prefab Quest Good (PhysBone count and PhysBone transforms Good, everything else Excellent)

GOOD TO KNOW
• Needs Modular Avatar and lilToon (both free, from the VRChat Creator Companion).
• The grip is set for the VRChat SDK sample avatar. If it sits wrong on yours, select Seats > UM_Seat_Hand > Seat and move or rotate it once.
• On a Quest avatar, use UM_StarUmbrella_Quest (the PC prefab with Quest materials is Quest Very Poor because of the particles).

SUPPORT
The grip angle, the opening and closing motion, the twinkle, the star rain or anything else not working as described in VRChat? Message me on Jinxxy and I'll fix it and send you the update for free.

AI DISCLOSURE (AI-Assisted)
The code that builds this umbrella (model, textures, Unity setup) 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.
