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

IMPORTANT: Delete the "Spline Mesher" folder completely when updating from v1.1.3 or older! Failing to do so results in unsolvable compile errors.

Changed:

- Improved readability of the Roll tool data point values in the scene view

Fixed:

- Issues with UI drawing if a Spline Mesher component is part of a prefab

- Mesh tangents not being calculated correctly, resulting in inconsistent normal mapping

1.2.1 (September 17th 2024)

Added:

- Demo scene, new examples:

* Bunting

* Rope

* Prayer flags

- Normalized gradients are now stored in the first UV's Z and W components, to be used in shader effects.

- Option to keep the generated mesh readable from script

Fixed:

- Component and tool icons not being found on Asset Store version

- Vertex colors of source mesh not being correctly retained over the vertical length of the mesh

- Vertex color visualization not being visible on backfaces

- Mesh rebuilding when the Spline was moved, even if the "On Spline Changed" rebuild trigger was not set

Changed:

- The Z and W components of the source mesh's UV is now also retained.

1.2.0 (September 9th 2024)

IMPORTANT: Delete the Spline Mesher folder before importing this update! It now installs as a package

Failing to do this results in all new content importing elsewhere

Added:

- Caps feature, spawns a prefab to the start or end of each spline

- Roll deformation feature: frequency and angle parameters. Plus spline tool to add angle data points.

- Vertex color data point functionality

- UV scale & offset parameters

- Added a "Collider Only" option, which skips the visual mesh creation.

- Rebuilder Triggers: Added "On UI Change" event (not upgradable, will be disabled when updating)

- Preferences UI, options to enable smoother rebuilding and automatic lightmap UVs

- Gear menu: action to rebuild all instances using the same mesh (in case of mesh changes)

- Index unit for Scale/Roll/Color data can now be set (Distance/Normalize/Knot).

Fixed:

- Trim start/end functionality not being strictly accurate

Changed:

- Settings for collision have moved, allowing expansion, and may need to be reconfigured

- Segment count now be manually specified

- Redesigned scene toolbar icons

- Warnings in the inspector if the Output object has no Mesh- filter or renderer. No longer auto-added.

- Inspector UI, option to add a new Spline Container if none is assigned

Removed:

1.1.1 (April 20th 2024)

Added:

- Rebuild Trigger flags, sets which sort of events cause the mesh to be regenerated.

- Public C# function to create a spline from an array of positions (CreateSplineFromPoints).

- Added a context menu option to the Spline Container component to quickly set up a default Spline Mesher.

- Option under GameObject/3D Object to create a new spline mesh.

Changed:

- QOL: Whenever the component needs to adds MeshFilter to the output object, it will also add a Mesh Renderer component if needed.

- Extra failsafes when importing into versions older than Unity 2022.3 without the Splines package installed.

- Context menu functions have been moved to a new Gear button in the inspector

- Sections in the inspector now behave as an accordion, expanding one closes all others.

Removed:

- Deprecated the "Rebuild on Start()" option (replaced by Rebuild Triggers flags).

Added:

- Demo scene, text description to each object explaining what is being achieved.

- Documentation now has a "Scripting" section, with example code and scripts.

- Inspector UI enhancements.

- Option to regenerate the mesh on Start(), required when prefabbing procedural meshes.

- Support for more than 65.535 vertices.

- A "SampleScale" C# function to the SplineMesher component.

- Scale tool now validates data points and resets them if a scale of 0 was found.

- Scale tool now supports multi-selection editing.

- A Spline Mesher component no longer requires 2 default scale data points. If no scale data is found, a default scale is assumed.

- Issue with geometry not generating for multiple splines if it uses more than 1 material.

- Vertex normals not being accurately rotated if the deformation scale was negative.

- Vertices at the very start/end of the spline possibly being deformed.

- Using a Box-shape collider with +1 subdivisions no longer shifts the collider when using the "Spacing" parameter.
