1.0.15 (September 9th 2026)

Added:

- Spline Curve Mesher: Option to use world-space projected UVs.

Fixed:

- Include Layer for colliders not being the correct default setting.

- Lightmapping possibly failing when Spline Fill Mesher components are present. Meshes are now converted back to 32-bit before lightmapping.

1.0.14 (July 24th 2026)

Added:

- Cube & Cylinder input mesh, option to invert the mesh (inside out).

Changed:

- Mesh construction is now skipped if the average scale of a segment is far too small. Instead mesh/colliders are cleared.

- Spline Curve Mesher: Improved blending of start/end when Splines are closed with a linear knot.

Fixed:

- Issue in Unity 6 where colliders would fail to generate under certain Spline conditions (regression since 1.0.13).

- End cap not being positioned at the actual end of the mesh if the "Even Only" distribution option was enabled.

1.0.13 (July 9th 2026)

Changed:

- Updated deprecated Unity API's in preperation for Unity 6.6+

- Lightmap UV generation now ignores components with the "Collider Only" option enabled.

- Errors will now be logged in a build if the platform doesn't support the SNorm8 of Float16 data formats.

Fixed:

- A minor gap appearing on closed splines of a considerable length.

1.0.12 (June 19th 2026)

Fixed:

- UI drawing error if a URP/HDRP project had invalid rendering layer names, causing the inspector UI to not fully render.

- Spline Curve Mesher: Normals of the final mesh not being correct if the Root transform was separate from the Spline transform and had a rotation applied.

1.0.11 (May 29th 2026)

Added:

- Cave Tunnel example to demo scene.

Fixed:

- Vertex colors being limited to half their intended value range (regression since 1.0.9).

1.0.10 (May 27th 2026)

Added:

- Spline Curver Mesher: Option to apply trimming also to the "Over Spline" scale curve.

- Spline Curver Mesher: Option to smooth linear knots under Distribution settings.

- Migration tool:

* Option to use prefabs from selection

* Option to only use root objects (skipping nested prefabs).

* Context menu option on Spline Mesher Standard components to convert a specific instance.

Changed:

- A gap no longer appears for closed splines with linear knots. Tangents are now blended between the first and last knots.

- An error is now thrown if a spline curve cannot be evaluated in the editor or development builds (NaN knot rotations or overlapping knots).

- Scale over Spline curve now better supports short curves through dynamic resolution scaling.

Fixed:

- Using the Trim End parameter causing intermediate flickering due to rounding errors.

- Error about scene not being loaded when having the Project Settings section open and unloading a scene with 1 or more Spline Mesher components.

- Adding a Spline caused scale/roll/colors/conforming data to be set up with the wrong index unit, until a component parameter was altered.

1.0.9 (May 6th 2026)

Added:

- "DestroyMeshes" public function, to destroy all meshes created by Spline Mesher components. Now also called in OnDestroy(). May be used for controlled cleanup.

- Menu items under Help/Spline Mesher Pro. To open the Help Window, Demo Scene, Preferences and Project Settings easily.

Fixed:

- Duplicate Spline Mesher instances not retaining the mesh from the original.

- Mesh not auto-rebuilding when assigning a Spline Container to a Spline Mesher component, when it had none.

- Light Probe and Rendering Layer Mask on created Mesh Renderer components not being the correct default setting.

- Normal map shading breaking on meshes in some cases when generating lightmap UVs.

Changed:

- Curve Mesher, no longer allows negative vertex color values. This is to add compatibility for external scripts needing to access the vertex colors from meshes.

1.0.8 (March 31st 2026)

Added:

- Spline Mesher class: AddCachedSpline, UpdateCachedSpline and RemoveCacheSpline functions are now public. These must be used Spline-related rebuild triggers are disabled.

Changed:

- Mesh generation now correctly bails out if a spline is provided with a NaN length (editor and development builds only).

- A null-check is now performed on Mesh Filter components, in case they were removed externally.

- A notification is now displayed if any of the Spline-related rebuild triggers are disabled, to indicate API calls are then required to manually handle spline changes.

Fixed:

- Input mesh not being correctly shaded if a negative scale was applied.

- Script compile error in Unity 6.4+ (regression since v1.0.7)

1.0.7 (March 26th 2026)

Added:

- Project Settings: option to hide the version update notice.

- Spline Mesh Segment component. Now has its spline curve range, tile length and tile count exposed

- Spline Mesh Segment component. Shorthand functions: GetSplineContainer, GetSpline and GetNearestPointOnSpline

- Spline Fill Mesher: Noise Direction parameter (to restrict displacement to only up- or down offsets) + Falloff parameter.

- Project Settings: Option to switch to 16-bit precision for vertex positions (for lower memory usage).

Changed:

- Meshes now use a compressed format, yielding a 50% reduction in memory usage. For lightmapped spline meshes uncompressed meshes are still required.

- Fill Mesher: minimum triangle size is now 0.05. The actual minimum value used scales up to 0.5 for splines longer than 50m.

- Fill Mesher: Lightmap UV is now generated in the same way as the Render UV. As this amounts to an identical UV to the Unity-generated one.

- Pivot points of Spline Curve Mesher segments are now at approximately the center of their curve segment

Fixed:

- Stray mesh objects remaining in memory when instantiating and destroying a Spline Mesher instance.

Removed:

- Fill Mesher output section: "Store Gradients in UV". No reason to disable this option, since the data used is always present anyway.

- Fill Mesher output section: Lightmap UV generation settings, rendered obsolete.

1.0.6 (March 17th 2026)

Added:

- Collision section, field to assign a Physics Material

- Curve Mesher: vertex color width gradient "Mirrored" option. If disabled the gradient runs from left to right.

- Fill Mesher: Reverse Faces and Flip Normals options.

Changed:

- Updated Collections package dependency to v2.6.2

Fixed:

- Migration tool, rotation value not being copied over.

- Deprecation warnings regarding "GetInstanceID" usage in Unity 6.4+

- Collider meshes of a duplicated Spline Mesher appearing to be linked to the original.

1.0.5 (March 13th 2026)

Changed:

- Curve Mesher: if a spline is used that's shorter than the input mesh, the mesh is scaled down to fit the spline. Previous behaviour was to skip mesh generation.

Fixed:

- Memory leak when using the Spline Curve Mesher component (regression since 1.0.4)

- Warning being spammed when trying to visualize the output segments and having the "Collider Only" option enabled.

1.0.4 (March 10th 2026)

Added:

- Spline Mesh Segment UI: Preview window for the created mesh.

- Collision: Include/Exclude layer masks

Fixed:

- Changing the "Keep Readable" option had no effect on already created meshes.

- Curve Mesher: Warning in the inspector when using an input mesh that is not readable while in playmode.

Changed:

- Improved handling of runtime mesh generation when input mesh is not readable.

- Minor performance improvement (~5%) by assuming the Root transform is not non-uniformly scaled/skewed (a warning is now displayed if it is).

1.0.3 (March 9th 2026)

Added:

- Segmenting Mode. Determines how the mesh is split into segments. (By Length, Every Tile, Specific and None).

- Cylinder input mesh: Caps creation even when the "Hollow" option is disabled.

- Vertex Color width gradient: Option to factor in the scale of the mesh, so the offset remains consistent.

Fixed:

- "SetSubMesh" warnings when altering the spline of a mesh with more than 1 material.

- Collider not scaling smaller than 1m (XY), if the "Collider Only" option was enabled.

- Scale Tool: Z-value of grid snapping settings not being respected.

- Extra segments created whilst editing a prefab not being removed when performing an Undo operation.

Changed:

- Spline data (Scale/Roll/Colors/Conforming) for removed splines is now cleared immediately.

1.0.2 (March 4th 2026)

Added:

- Support for usage with prefabs.

- Scale Tool: support for natively grid snapping scale values.

Changed:

- Splines shorter than 1m long are now allowed.

- SplineMeshContainer and SplineMeshSegment components now have an inspector UI showing relevant stats.

- The warning regarding prefabs and procedural meshes can now be dismissed.

- SplineMesher base component is now prevented from being manually added to a GameObject.

Fixed:

- Using the same Root transform for a Curve Mesher and Fill Mesher resulted in both trying to adopt eachother's output meshes.

- Collider some times not appearing to be generated, if the "Custom" was first selected with no mesh assigned.

- Input mesh alignment not correct when also applying a rotation.

- Script error when Bakery was installed (missing assembly reference).

- Leak error messages when calling Rebuild() from a script whilst adding new Splines.

- Error thrown when deleting the last point in the Scale editor.

1.0.1 (March 2nd 2026)

Fixed:

- Normals of Cube input mesh being flipped on the left face. Resulting in a gap in colliders.

- Several meshes in the demo scene inadvertently using materials from the Standard package.
