Release 3.10.3

Summary

SDK Version 3.10.3 brings Toon Standard improvements, the VRCRaycast component, and exposes VRC+ subscription status to Udon!

Features

• Added the VRCRaycast component.
  • It allow avatars to fire rays through the scene that hit against colliders in the world or on players. A transform is positioned at the point the raycast hits.
  • This provides similar functionality to FinalIK, but is much more optimized and easier to use.
• The Toon Standard shader now supports a "Color Mask" property.
  • This allows you to apply different Tint values based on an RGB(A) mask texture.
  • Every channel can additionally be configured with Emission.
  • The additional Tint can be applied in Multiply and Additive modes.
  • Color masks without an alpha channel will automatically disable the 4th Tint option to avoid confusion.
• Added an isVRCPlus property to VRCPlayerApi to allow Udon to query if a user has an active VRC+ subscription.

Fixes & Changes

• Fix String and Image URL loading features not working in ClientSim since 3.10.2.
• Mirrors now render in Camera.onPreCull instead of OnWillRenderObject to match the 2026.1.3 client.

Fixes & Changes from 3.10.3-beta.1 to 3.10.3-beta.2

• Improvements to VRCRaycast:
  • Changed the editor gizmo to be orange instead of blue.
  • Added avatar animator parameters set by VRCRaycast:
    • {Name}_Hit is a boolean parameter set to true while the ray is hitting a collider and false while it isn't.
    • {Name}_Ratio is a float ranging from zero to one that gives the ratio of the full distance covered by the raycast. For example, if the hit is 50% of the way along the ray's maximum distance, this value will be set to 0.5.
    • {Name}_Distance is a float giving the actual distance traveled by the ray in world units before it hit something.
  • Fixed the result transform facing the wrong way when the ray misses when configured to snap on miss.
  • Renamed Positioning On Miss to Behavior On Miss to better reflect that this option also affects rotation while Apply Rotation is turned on.
  • VRCRaycast now behaves correctly in SDK projects where domain reloading is disabled.
  • Added an option to allow raycast distance to change with the Z scale of the transform the component is attached to.
    • It's still limited to a maximum distance of 1000 units.
  • Added public C# properties to the raycast component for user-made SDK tooling.

Fixes & Changes from 3.10.3-beta.2 to live

• Removed Disable On Miss from VRCRaycast, since it's redundant now that avatar animator parameters are available instead.

Known Issues

• In rare cases, you may see an "All pipe instances are busy" error while building. This is a Unity issue - restarting your editor and trying again should fix it.
