Wagasa Umbrella - Folds Open and Closed, Cherry Petals Fall | VRChat

A Japanese janome-gasa (bull's-eye umbrella) with 48 bamboo ribs and oiled paper. Five-color threads are laced inside, the handle is wrapped in silk, and the top has layered paper caps and a tied cord.

Turn "Open" OFF in the menu: the ribs swing down around the top hub, the paper folds inward between them, and the runner slides down toward the handle (about 1.2 seconds). Turn it ON and it opens again.

While it is open, cherry petals flutter down around the umbrella (done with a shader, no particles). Look up from below and the light shows through the paper.

Features

• Opens like a real umbrella: the ribs turn around the top hub, and the stretchers keep their length while they push the runner up or pull it down (the runner height is calculated)
• When closed, the paper folds inward between the ribs into a slim shape. You can also see every in-between shape while it folds
• 40 cherry petals fall from a ring outside the edge of the umbrella, turning as they fall (toward the world's down direction; they do not pass through the paper). "Cherry Petals" turns them on/off, and they disappear when the umbrella is closed
• Translucent paper: seen from below, the light from above shows through, with the ribs and five-color threads as shadows
• Details: 48 ribs and stretchers, rib tips, ridge lines along the ribs, the bull's-eye band (narrow on vermilion, wide on indigo), a flowing-water pattern, black lacquer edge, five-color lacing (red, yellow, green, blue, purple), layered paper caps and cord, brass and black lacquer hubs, bamboo nodes and a silk-wrapped handle
• The folding is one mesh and one material, all done by a shader (no blend shapes, bones, particles or PhysBones). No lilToon needed (custom shaders included)
• 2 colors, both included: vermilion (vermilion paper, off-white band) / indigo (indigo paper, off-white band)
• Original design

How it opens and closes

• The umbrella is one mesh. Each part is marked as "follows a rib", "stretcher", "runner", "paper", "thread" or "does not move", and the shader turns or slides each part by the opening amount (0 to 1).
• The ribs turn around the top hub and drop about 65 degrees when closed. The stretchers keep their length, so the runner height is "the stretcher length below the point where it meets the rib": it rises when the umbrella opens and slides down when it closes, like a real umbrella.
• The paper folds inward between the ribs. Ribs, stretchers and threads at the same angle move inward by the same amount, so nothing sticks out of the folded paper.
• Open / close is a synced Bool blended over 1.2 seconds, so everyone sees the same movement.

Menu (English menu prefab)

• Wagasa Umbrella > Show: hold / put away the umbrella
• Wagasa Umbrella > Cherry Petals: petals on/off (they dance only while it is open)
• Wagasa Umbrella > Open: open <-> closed (folds or opens in about 1.2 s; open at first)

What's included

• Prefabs x 2 colors (vermilion, indigo)
• FBX, textures (color atlas), 2 custom shaders (umbrella, petals), animations
• English-menu prefabs (_EN) next to the Japanese-menu prefabs. Use one or the other on an avatar, not both.
• Instruction manual and Terms of Use in English and Japanese

Specs

• Triangles: about 10,000 (9,968: umbrella 9,888, petals 80)
• Materials: 2 (umbrella, petals) / renderers: 2
• Synced parameters: 3 bits (Show, Open, Cherry Petals)
• 0 particles, 0 PhysBones, 0 AudioSources, 0 bones
• Performance rank: PC Good overall (checked in the Unity test)
• Size: about 960 mm across when open, about 825 mm long (real size)

Requirements

• Unity 2022.3.22f1 (an avatar project made with VRChat Creator Companion)
• VRChat SDK (Avatars) 3.10 or later
• Modular Avatar 1.18 or later
• lilToon is not needed (custom shader included)

Please note

• PC only. Not supported on Quest / Android.
• No hand pose is included.
• It is real size (about 96 cm across). For small avatars, scale "..._Model" down (the petals scale with it).
• The umbrella is built tilted 19 degrees from its shaft. Rotate "..._Model" to point the tilt the way you like.
• The closed shape is made to look right; it is not a real fold that keeps the paper area.
• The petals do not pile up on the ground or on the umbrella. Rain is not included.
• If a viewer's Safety settings hide shaders, the umbrella is shown open with a standard look and the petals are hidden.
