Settings
| Setting | Default | Description |
|---|---|---|
| Increase Bounding Sphere | 7 | Expands the prototype bounding sphere used for frustum culling. Increase it when scale changes or shader deformation makes objects disappear too early. Values below 0 are clamped to 0. |
| Get Additional Shadow | DirectionLightShadowVisible | Controls how shadows remain visible when the object is outside the camera frustum. Appears only when the prototype has Shadow and global Is Shadow Casting is enabled. |
Get Additional Shadow modes
| Mode | Extra setting | Description |
|---|---|---|
None | None | Does not add extra shadow visibility outside the camera frustum. |
MinCullingDistance | Min Culling Distance | Disables culling below the configured camera distance so nearby shadow casters stay available. Default is 50. |
IncreaseBoundingSphere | Increase Shadows Bounding | Expands shadow bounds separately from render bounds. Default is 0. |
DirectionLightShadowVisible | Directional Light | Uses the scene directional light to decide which off-frustum shadows should stay visible. This is the default mode. |
DirectionLightShadowVisible is selected, the inspector uses the scene Additional Data directional light provider.
If no light is assigned, the inspector shows Find Directional Light and a Directional Light field.
When to adjust it
Increase the bounding sphere when objects disappear too early because:- the object is scaled larger than its prefab bounds;
- the shader bends or offsets vertices;
- shadows need to remain visible outside the camera frustum.
