A year in the making, SleightlyBall is a "spring-joint ball" like system built for VRChat users. It is the most customizable, modular, feature-rich ball system with an automatic setup tool, allowing for 2 step installation without any VRChat 3.0 or advanced Unity experience whatsoever.

This is a system and does not include any balls in its own package. Please import your own/purchase them separately.

The Japanese Lantern and Aqua Ball featured in the showcase are also for sale!


  • Drag and drop setup - works with any object, not just balls
  • Supports balls on either (or both) hands
  • Supports up to 8 balls per hand
  • Multiple anchor points around the body - pass the ball between hands, head, chest, even the feet or world
  • Configurable ball distance and/or strength from in-game
  • Constrain any of your anchors in world space or local space and still control balls to and from them
  • Mesh based physics (not particle) which works with any object, including collision, bounce, and gravity toggles
  • Throw/Shoot modes you can toggle between
  • Share your balls with other players! Constrain it to them, or make it orbit them
  • FBT Mode options to also control the balls with your feet
  • Smart Dynamic Audio supports up to 8 audios both played aloud or locally
  • Pilot the ball like a drone without using a constraint-based piloting system, meaning less desync
  • Toggle between simple/complex gesture sets in case you want to manage less gestures
  • Automatic Write Defaults detection and compatibility with both on/off
  • Drag and drop gesture remapping to any configuration you prefer
  • Automatically disable facial expressions while controlling the balls
  • Automatically optimizes your parameter memory saving up to 46 memory other systems would use. Up to 54/59 (91.5%) of the menu options can fit within 8 memory!
