Halloween Witch Trace | Pumpkin Footsteps, Ghosts & Bats | Shinano | PC VRChat

Witch Trace v1.0 / Craft Setup / October 1, 2026

Halloween footsteps for Shinano v1.02 / Windows PC VRChat

Leave glowing white-gold vines, leaves, moons and orange pumpkins along your path. Pale blue ghosts sway upward, two small bats appear per step with independently randomized sizes, soft blue-white haze lingers low, and gold/icy-blue particles twinkle around the prints and in the air. Mirrored left/right prints are included.

REQUIREMENTS

Tested with Unity 2022.3.22f1, VRChat Avatars SDK 3.10.4, Modular Avatar 1.18.7 and NDMF 1.14.8.

Install SDK and MA separately. Product PC shaders are included. Install the avatar's own dependencies separately.

Shinano is sold separately. Standalone Quest / Android are not supported.

Fitted for standard-size Shinano v1.02 on flat floors. Other avatars, altered height/proportions, stairs and slopes are not fitted or verified.

INSTALLATION

1. Back up your avatar project. Install SDK Avatars and Modular Avatar through VCC, then import your purchased Shinano normally.

2. Import every asset in WitchTrace_PC_v1_0.unitypackage.

3. Find WitchTrace_Shinano_PC_v006_LOCAL_TEST at:

Assets/CraftSetup/WitchTrace/Walking_Shinano_v006/WitchTrace_Shinano_PC_v006_LOCAL_TEST.prefab

4. Place ONE copy directly under the avatar root, not inside a foot bone. Keep its outer local position/rotation zero and scale one.

MA adds the controls automatically; do not manually replace your avatar's FX controller or Expressions menu.

5. Build & Test, then turn on Expressions > ウィッチトレース (Witch Trace). Default OFF.

6. To show it to other people, upload the avatar online as Private and wear it from Uploaded.

Validated internal v006 / LOCAL_TEST names are retained for reference stability. The sale version is v1.0.

Do not delete older-named dependency folders, install duplicates or leave older Witch Trace versions on the same avatar.

If Fairy Trace or another footprint effect is installed, enable only the effect you want to use.

CONTROLS / BEHAVIOR

One saved, network-synced Bool (1 bit) controls the complete effect. No individual effect toggles or in-game fitting/color/quantity controls.

OFF stops new births; already-emitted particles fade naturally. Standing still does not emit continuously.

Footprints remain at their birthplace until they fade. Each bat independently samples size, position and delay.

Configured wingspan 27-37.2mm, life 2.7-3.2 seconds, birth delay 0.12-0.30 seconds; these are settings verified in Unity.

Emission does not illuminate the world. Floor, lighting and background affect appearance.

Ground colliders and foot height are required; unusual floors, sitting and lying poses can prevent expected emission.

VERIFICATION / VISIBILITY

PC VRChat on Shinano: walking footprint placement, combined appearance and fading after stopping checked on October 1, 2026.

Unity: contact detection, menus/sync configuration, two random-size bats per contact, birthplace retention and expiry verified.

Witch Trace and the three-product combination have not been tested from a friend's client. Remote toggle delivery, stereo VR, stairs/slopes and measured GPU/FPS cost remain unverified.

SDK Build & Test avatars are visible only to you. Online upload needs a VRChat account with New User rank or higher.

Other users' Safety/avatar/particle settings can hide effects. The toggle is configured to sync, but contacts and random particles run locally on each device; exact positions and timing are not guaranteed to match.

CONTENTS / TERMS

One fitted prefab containing both feet, meshes, materials, PC shaders, textures, animations and menu; Japanese/English instructions, specifications, terms and changelog.

No Shinano avatar, clothes, shoes, hair, world, SDK, MA, Blender/FBX/GLB sources or photography pose.

Modification, images/videos and monetized streaming allowed. No redistribution, resale or Public avatar inclusion. See LICENSE_EN.txt.

Generative AI used for concepts and Tripo mesh bases; flattening, materials, geometry refinements, ground contact, motion, haze, sparkles and menus were adjusted for this product.

SUPPORT

No effect: check the menu toggle, MA installation, placement under the avatar root, floor collider and Unity Console errors.

Offset effect: check avatar size, prefab Transform and modified feet/shoes. Pink: import all dependencies and use Windows PC.

PRODUCT SPECIFICATIONS

Witch Trace v1.0 / both feet

4 distinct source meshes: left stamp, right stamp, ghost, bat. Particle billboards are separate.

Source mesh triangles: Ground_L 2; Ground_R 2; Ghost 2,300; Bat 6,212. Total 8,516 across the four unique meshes. Particle instances multiply rendered triangles.

20 Particle Systems / 14 visible particle renderers / 5 shared materials

2 native VRC Raycasts / 6 native VRC constraints / 0 PhysBones / 0 real-time lights

1 additional saved/synced Bool bit / default OFF

Configured capacity: 362 particles including 14 invisible carriers.

Maximum configured visible triangles: 276,672 (16 stamps + 12 ghosts + 24 haze + 40 bats + 256 twinkle billboards).

Actual load depends on the active particle count and transparent layers. This upper bound is NOT an FPS measurement or a low-cost claim.

Both bats per step use independent random sizes; up to 20 bats per foot, not a two-total cap.

GALLERY

The cover is an AI-assisted layout using the actual Unity preview; fine details can differ. Unedited VRChat and Unity captures show the actual product. The GIF is a normal-speed excerpt from the October 1, 2026 VRChat recording; no synthesized motion. The final concept illustration is a design reference, not an in-game screenshot.

Japanese image labels: 魔女の足あと = Witch's footsteps; しなの調整済 = fitted for Shinano. The product includes the footprint effect only, not the avatar or outfit.
