Please do consider leaving a REVIEW if this update proved to be beneficial. This in an invaluable way to support future development and helps make these complementary updates possible!

1.2.0 (July 15th 2026)

Added:

- New core Terrain Layer Masking feature, allows to include/exclude objects from terrain layers.

- Respawn Triggers, determine what events will trigger a respawn. This may be used for advanced scenarios that require full control.

- Modifier add menu: Presets for Random Y/XYZ Rotation and Scale Variation 20%.

- Snap To Grid modifier, option to use the Scene View grid snapping system.

Changed:

- Script: "RespawningMode" enum was renamed to "SplineChangeTrigger"

1.1.8 (July 7th 2026)

Added:

- Menu items under Window/Spline Spawner to open the demo scene or edit the masking layer names.

Changed:

- Minor code updates for Unity 6.5+;

Fixed:

- Size of prefabs with a LOD Group not just being calculated from LOD0, resulting in larger spacing than expected.

- Compute shader warning on some platforms (otherwise harmless).

1.1.7 (April 16th 2026)

Changed:

- Drop To Collider modifier, minor performance improvement.

Fixed:

- Additional meshes used for LOD0 not contributing to the calculated size of a prefab.

- Drop To Collider modifier, slope limit min/max values not accepting manual input.

1.1.6 (March 4th 2026)

Added:

- Support for usage with prefabs.

- Icons for inspector sections.

Changed:

- Minimum allowed spline length is now 0.25m

Fixed:

- "Create" menu item not placing the newly created spawner in a prefab's hierarchy.

1.1.5 (December 14th 2025)

Changed:

- Object pools are now cleared when disabling the Spline Spawner component, or when closing its inspector.

- Prefab section now shows a warning if a model asset is used (as this cause the entire file to be instantiated).

Fixed:

- Remnant objects from object pools being unintentionally saved if the "Hide Instances" option was disabled.

- Instance Count Mode: Specific. Spacing will still being incorperated, resulting in a different instance count than specified.

1.1.4 (December 8th 2025)

Added:

- On Curve distribution: lanes feature, allowing to spawn objects in multiple parallel lines.

- Inside Area distribution: "Allow Overflow" option, if enabled objects can overlap the Spline's curve.

- Inside Area distribution: "Tightness" parameter, if set to 1 objects are placed in a hex pattern.

- Inspector UI: Warning message when nothing was spawned using the current configuration.

Changed:

- Mask layer names can now be edited in Project Settings->Tags and Layers.

- Inside Area distribution, improved overlap detection method (existing spawns will change slightly).

Fixed:

- Offset modifier: Z-axis noise offset not taking effect.

1.1.3 (December 1st 2025)

Added:

- Spline Spawner Mask inspector UI: list of all spawners being affected by it.

Changed:

- Distribution performance increased by 200-400% through key optimizations.

Fixed:

- Masking layers names reverting to default when closing the editor

- Masks being able to trigger respawns during the building process

- Script error when using a Mask with invalid splines (shorter than 1m or 0 knots)

- On Curve Distribution: Rotate To Fit "Y" option not correctly levelling the rotation of objects.

- Rotate To Fit: Not correctly orienting the objects if a spacing was used

1.1.2 (October 16th 2025)

Added:

- Startup behaviour options: None, Respawn and Respawn Randomized.

- Mask: Update On Enable option, for runtime spawning functionality

Changed:

- Toggling masks now only triggers respawns if they are selected in Edit mode.

Fixed:

- Issue with spawners as child objects of other spawners being misinterpreted as orphaned objects.

1.1.1 (October 6th 2025)

Fixed:

- Prefab spawning warning not refreshing when Root transform changes

- Spawning not taking effect for prefabbed spawners, even if the Root transform was an external (non-prefab) object.

1.1.0 (September 24th 2025)

Added:

- Look At modifier, rotates objects towards a specific target.

- SetSplineContainer() functions to correctly handle changing the spline container of a Spline Spawner component.

- Improved support for usage in prefabs. Respawning is now disallowed for prefab instances, but possible for prefab source objects.

- Radial distribution: Min Radius, Angle Range and Height Offset parameters

- Rotation modifier: Option to lock X/Y/Z rotation axis.

- Offset modifier: Noise-based offsetting.

- Radial distribution, added "Border Accuracy" performance balancing option.

Changed:

- The minimum required version of the Mathematics package is now 1.3.2 (will auto-upgrade).

- The 'splineContainer' field on the Spline Spawner and Spline Spawner Mask components can no longer be set manually. Use the SetSplineContainer() function instead.

- Spline Instance Container, polished inspector UI and added tooltips to options.

- Implemented safety check when attempting to spawn prefabs with one or more Spline Spawner Mask components.

- Optimized performance regarding masks. They'll now only respawn spawners physically intersecting with the mask.

- Radial distribution, changing the 'Center' parameter no longer clips objects from the opposite end.

Fixed:

- Leak Detection console messages cropping up in some cases.

- Grid distribution, default object rotation not aligned with row/column direction.

- Script error when no spawning Root transform was set.

- Duplicating a Spline Spawner without a Root transform assigned would not duplicate the objects correctly.

- Spawning prefab variants didn't correctly link the objects to the source prefab.

- Scaled child objects in prefabs did not correctly contribute to the calculated size of the prefab.

1.0.0 (August 11th 2025)

Note: Updating from the preview version is not supported, delete it before importing.

All component settings and configurations will be lost due to data structure changes.

Added:

- Masking functionality, other splines with a SplineSpawnerMask can define masking layers. Spline Spawners can filter by them.

- UI, drag & drop box for adding new prefabs

- Snap to Colliders modifier, added "Direction" option. Making it possible to snap down from the Spline curve.

- Height Filter modifier, restricts spawning within the configured height range.

- On Curve distribution, spacing can now be set between a minimum and maximum value.

- Scale, functionality to scale over a curve

- On Knot distribution, options to select which knots to spawn on (eg. first & last, specific range, etc).

Changed:

- Inspector UI has been overhauled and polished

- Distribution settings seed can now be randomized

- Distribution modes now have performance/accuracy preference options

- Prefabs array is now a List, for easier insertion and deletion of objects

- Performance of spawning inside a Spline's area has improved 400-1800%

Fixed:

- Duplicating a Spline Spawner component would inadvertently link the original and copy's modifier stack.

- Modifier stack not being saved to prefabs or supporting prefab overrides.

- Modifier stack not supporting undo/redo operations
