The purpose of this plugin (written in C++) is to provide a way to define meshes using Splines. It is not SplineMesh but procedural meshes with a parametrized definition adapted to the curvature of the splines used.

In realtime the modifications to the splines are reported on the generated meshes. 

The module can be used in Runtime and in Editor mode, the only difference is that in Editor mode, you can generate StaticMesh instead of working only with ProceduralMesh.

Feature videos

The plugin is required to use the following example projects.

ExampleProject (UE5 only – Meshes are duplicated to see subdivisions using a wireframe material superimposed with a black material)

ExampleProjectWithoutMaterial (UE5 only – This second example is without duplication of the meshes and let you play directly with the generated objects)

Release notes:

  • V1.1 (19 April 2022) – Fix: runtime bug corrected
  • V1.2 (25 April 2022) – Optimizations on thread management for a smoothness experience – more options for static mesh generations. Fix: missing segment in rare cases during mesh generation.
  • V1.3 (20 May 2022) – New feature: Array object which can instantiate Actors/Meshes along a spline and a new plugin version for Unreal V4.27
  • V1.4 (02 June 2022) – Fix: bad Array object locations using closed splines
  • v1.5 (22 August 2022) – New feature: Array support Instanced Static Meshes and Hierarchical Instanced Static Meshes (culling distances are exposed for these options)
  • v1.7 (08 June 2023) – UE5 only – New feature: Support of DynamicMesh with a new Object (SmartDynExtruder) to keep compatibility with previous projects (a part of the code is duplicated but a refactor will be made for ProceduralMesh). Fix – editor crash in runtime mode when the stop was triggered during mesh generation.
  • v1.8 (05 June 2024) – Fix – reload some splines in editor scene was broken in some cases – Support of UE versions 5.3 and 5.4

Known Bugs:

  • V1.7 and below – The option for a unique Material in ProceduralMesh is broken (only a part of the mesh is modified, a fix will be published)

这个插件（用C++编写）的目的是提供一种使用样条定义网格的方法。 它不是SplineMesh，而是具有适应所用样条曲率的参数化定义的程序网格。

在生成的网格上实时报告对样条的修改。 

该模块可以在运行时和编辑器模式下使用，唯一的区别是在编辑器模式下，您可以生成StaticMesh，而不是仅使用ProceduralMesh。

如有任何疑问或问题，请与我联络：contact@infine-it.fr

专题短片

该插件需要使用以下示例项目。

例如项目 （仅限UE5-使用叠加了黑色材质的线框材质复制网格以查看细分）

例如，材料以外的 （仅限UE5-第二个例子没有网格的重复，让您可以直接使用生成的对象）

发行通知书:

  • V1.1（2022年4月19日）-修正：运行时错误修正
  • V1.2（2022年4月25日）-优化线程管理以获得平滑体验-更多静态网格体生成选项。 修复：在网格生成过程中极少数情况下缺少分段。
  • V1.3（2022年5月20日）-新功能：可沿样条实例化Actor/网格体的Array对象和虚幻V4.27的新插件版本
