Undertale - Style Soul Heart

Three ready-to-use VRChat heart prefabs that sit inside the chest, show through the body, and include mesh + light color sliders.

❤️ VRChat Chest Heart Accessory — 3 Prefab Pack

A soul-style heart you wear inside your avatar’s chest — visible through the
body — with full Expression Menu control via VRCFury. Choose the look that
fits your avatar: retro pixel, clean geometric, or textured realistic.

• 3 prefabs — pick ONE for your avatar:

• PixelHeart (pixel-style mesh)
• BasicHeart (stylized geometric heart)
• RealisticHeart (detailed 3D heart)
  • Chest-mounted with VRCFury Armature Link
  • Custom FlareTinted shader — see-through body effect + visible black/dark colors
  • Toggle heart mesh On/Off
  • Toggle Point Light On/Off (independent from mesh)
  • Mesh Hue slider (saved) — full color cycle on the heart material
  • Light Hue slider (saved) — match or contrast the glow
  • Exclusive heart tag — one main heart style at a time when using shared toggles

🎮 IN-GAME CONTROLS (Expression Menu)

Each prefab adds its own menu prefix:

Pixel_Heart/On, Point Light, Mesh Hue, Light Hue
Basic_Heart/On, Point Light, Mesh Hue, Light Hue
Realistic_Heart/On, Point Light, Mesh Hue, Light Hue

Mesh Hue: 0% ≈ white, then rainbow hue on the mesh tint.
Light Hue: same style control for the point light color.
