Spline Mesher

📄 Documentation | 💬 Forum thread

A straightforward and powerful tool for spline-based mesh deforming. Essential for 3D world building. Built around Unity's native spline tool, making it intuitive to combine with other tools or gameplay logic.

> Provide the component with a spline and an input mesh, and it gets continuously repeated along the spline.

Build fences, pipes, paths, cables and much more!

🗯This tool is under development, based on user feedback, and is offered at a reduced price.

🔗 Features

• Creates one continuous object, no clutter of GameObjects

• Automatic box-shape collider generation

• Recalculated normals, ensuring correct lighting

• Downward snapping to colliders

• Per-point scale adjustment

• Rebuild events exposed in the inspector, and through C#

Features a cleanly designed inspector UI, with tooltips and undo/redo support.

✔️ Supports

• Runtime generation (no API calls required, simply alter the spline)

• Multiple material support (aka sub-meshes)

• Multiple splines within the same container

• Negative scaling support (eg. guardrails mirrored on either side of a track)

🚧 Limitations:

• Usage of created meshes in prefabs requires exporting them to an FBX file using the Unity's "FBX Exporter" package*. Because Unity strictly saves procedural meshes in scenes.

• Constant regeneration every frame may be prone to performance issues.

* Automatic FBX exporting is slated for implementation, currently it does not support collider exporting.
