• Player Script component

The following restrictions apply to item components:

• RidableItem restrictions
  • AvatarOverrideAnimation of RidableItem is not used
• ScriptableItem restrictions
  • *-Compat series APIs cannot be used
    • For details, refer to Script Reference

Rendering-related components

For rendering-related components, MeshRenderer and MeshFilter can be used.

• Items must have at least one active MeshRenderer.
• Number of MeshRenderers in one item must be 32 or less.
• Only Materials settings are used for MeshRenderer settings.
• Area where Mesh exists must be within (5, 5, 5).

Collision-related components

For collision-related components, BoxCollider, SphereCollider, CapsuleCollider, and MeshCollider can be used.

• Materials of all Colliders are not used.
• MeshCollider must be Convex, and the specified Mesh must have 255 or fewer Triangles.
• Cooking Options of MeshCollider are not used.

• Area where Colliders can exist must be within (5, 5, 5).
• Behavior can be specified by attaching Shape components to Colliders.
• Colliders with Is Trigger on and without Shape components are not used.

Physics behavior-related components

Rigidbody Component is only used when Movable Item component is added.
The following properties of the Rigidbody component can be changed:

• isKinematic: Items uploaded with this property turned off will have physical behavior.
• useGravity : Items with physics behavior uploaded with this property turned off will ignore gravity.
• Mass: Sets the mass of items with physical behavior.

Other property settings will not be reflected, and the default values of the Rigidbody component will be used.

Whether an item is affected by gravity can also be dynamically toggled via script. For details, refer to Script Reference.

World components

For world components, the following components can be used:

• Standard Main Screen View component
• Mirror component
• Shape components
• TextView component

Text in TextView must be 1kB or less.
