Spline+ 样条线

Spline+ Features include:

• Quickly and easily change the spline mesh’s materials
• Change the mobility options (Static, Stationary, Movable)
• Change collision settings from No collision, Query only, Physics only or Both
• Use either curvy spline math or linear spline math
• Change the Random Seed to randomize some factors of the spline

Spline Generation:

• Use either Repeating meshes, Repeating Equally Stretched meshes and Periodic placement of meshes:

1. Repeating: Meshes are connected and bend, only stretches the last mesh to the end of the spline.
2. Repeating Equally Stretched: Stretches all meshes in the spline equally to reach the end of the spline.
3. Periodic: Will spawn meshes periodically along the spline.

• Use either Static Meshes or Hierarchical Static Meshes on the Periodic generation type
• Ability to add Start and End meshes on the start and end of the spline

Extra options:

• Ability to spawn Meshes or Actors
• Ability to change the mesh’s forward axis
• Spawn multiple different meshes/actors in the same spline
• Spawn multiple meshes sequentially
• You can set a gap distance between meshes/actors between their pivot points, or between their bounding boxes
• Twist amount determines how many times the actor will twist along the spline
• Force Z Vertical tickbox
• Flip mesh tickbox for the start and end meshes
• Ability to spawn the first, middle and last meshes/actors
• Ability to add more meshes along the length of the spline, squishing them so they don’t exceed the length
• Add offsets for transform and rotation, randomised offsets for transform and rotation, or both

Included is an Example Feature Zoo scene

样条+功能包括:

• 快速轻松地更改样条网格的材质
• 更改移动选项（静态、静止、可移动）
• 从无碰撞、仅查询、仅物理或两者更改碰撞设置
• 使用曲线样条数学或线性样条数学
• 更改随机种子以随机化样条的一些因子

样条生成:

• 使用重复网格、重复同样拉伸的网格和网格的周期性放置:

1. 重复：网格连接并弯曲，只将最后一个网格拉伸到样条的末端。
2. 重复同样拉伸：同样拉伸样条中的所有网格以到达样条的末端。
3. 周期性：将沿着样条线周期性地产生网格体。

• 在周期性生成类型上使用静态网格体或分层静态网格体
• 能够在样条曲线的开始和结束上添加开始和结束网格

额外选项:

• 生成网格体或Actor的能力
• 能够改变网格的前轴
• 在同一样条中生成多个不同的网格/actor
• 依次生成多个网格体
• 您可以在网格/actor的枢轴点之间或边界框之间设置间隙距离
• 扭曲量决定actor将沿着样条扭曲多少次
• 力Z垂直刻度盒
• 翻转开始和结束网格的网格复选框
• 生成第一个、中间和最后一个网格体/actor的能力
• 能够沿着样条的长度添加更多网格，压扁它们，使它们不超过长度
• 为变换和旋转添加偏移量，为变换和旋转添加随机偏移量，或两者兼而有之

包括一个示例功能动物园场景

Documentation: Spline+ Documentation

Spline+ is a high quality blueprint system that takes in Meshes, Blueprints and Materials and spawns or stretches them along a spline you can easily control.

This pack comes with an example map and basic meshes to demonstrate Spline Plus’ features.

The intentions of this pack is to be able to quickly add detail to your scenes or games. It comes with the functionality to populate one spline with many meshes/actos as to not having to place them by hand.

Spline+ is a highly customizable tool that allows for easy additions for new features to match your use case.

BUGS:

• In Unreal 5.2 onward there is a bug stopping vertex colours from being used on Spline+’s ‘Repeating and Repeating Equally Stretched meshes’

• In Unreal 5.4.0 Epic changed how splines work slightly, it no longer understands anything when you move an anchor point. Here is a link to the bug, click vote on the vote box so epic sees it and can hopefully fix it: https://issues.unrealengine.com/issue/UE-212309 One temporary workaround is when you move an anchorpoint, click the ‘Input spline points to construction script’ tickbox on and off again. It should re-fresh the logic and at least works temporarily.

Spline+是一个高质量的蓝图系统，它接收网格体、蓝图和材质，并沿您可以轻松控制的样条生成或拉伸它们。

这个包附带了一个示例地图和基本网格来演示样条+的特性。

这个包的目的是能够快速添加细节到您的场景或游戏。 它具有用许多网格/actos填充一个样条的功能，而不必手工放置它们。

Spline+是一个高度可定制的工具，允许轻松添加新功能以匹配您的用例。

臭虫:

• 在虚幻5.2之后，有一个错误阻止顶点颜色被用于样条+’S’重复和重复同样拉伸的网格’

• 在虚幻5.4.0中，Epic稍微改变了样条的工作方式，当您移动锚点时，它不再理解任何内容。 这是一个链接到错误，点击投票框，所以史诗看到它，并希望能修复它: https://issues.unrealengine.com/issue/UE-212309 一个临时的解决方法是，当您移动锚点时，再次单击”输入样条点到构造脚本”复选框。 它应该重新刷新逻辑，至少暂时起作用。
