This plugin uses precedural generated meshes based on splines. They can be provided with animations and particle emitters, which are following the spline. In addition you can easily create seamless tributaries, which can branch and join from and to any other spline flowing in the same direction. You can create very easily your own materials (Plugin provides example starting code). Also there is an automatic spline generation feature, when using unreal landscapes. A spline becomes generated dependent on specific heightmap information (like tangents). When you have some additional questions have a look at the video or post them here.

Fix for unreal version 4.26.2 and 4.27.1:

• Spline generation did not work properly in some landscape scenarios. Updating heightmap reading code fixed the issue.

Update 1.01

• BUG FIX : All types of landscapes work properly now (Bug when using landscapes > 8×8 Sections)
• IMPROVEMENT : New spline generation algorithm with improved performance (Make sure to select correct river width for best results)
• FEATURE : Plugin keeps track of deleted spline points. Tributaries become automatically updated when deleting spline points

此插件使用基于样条的先前生成的网格。 它们可以提供动画和粒子发射器，它们遵循样条曲线。 此外，您可以轻松创建无缝支流，这些支流可以在相同方向流动的任何其他样条之间分支和连接。 您可以非常轻松地创建自己的材料（插件提供示例起始代码）。 使用虚幻地形时，还有一个自动样条生成功能。 样条曲线取决于特定的高度图信息（如切线）生成。 当你有一些额外的问题，看看 短片 或者把它们贴在这里。

修复虚幻版本4.26.2和4.27.1:

• 样条生成在某些地形场景中无法正常工作。 更新高度图阅读代码修复了这个问题.

更新1.01

• 错误修复：所有类型的地形现在都能正常工作（使用地形>8×8部分时的错误）
• 改进：具有改进性能的新样条生成算法（确保选择正确的河流宽度以获得最佳结果）
• 功能：插件跟踪已删除的样条点。 删除样条点时，支流会自动更新
