How to Use

To view an example of the tool in use, see the Demonstration map located in WaterfallTool > Maps.

Drag and drop the Blueprint “BP_WaterfallTool” into the viewport (located in WaterfallTool > Blueprints).

Use the spline points to adjust the height and angle of the waterfall.

The bottom spline point will be automatically locked to the ground if Ground Check is ticked on.

Change settings in the Details Panel as desired:

• Waterfall Settings

  • Ground Check: Toggle if the waterfall should automatically stay on the ground

  • Easy Scale: Scales the width of the waterfall

  • Water Color: Change the colour of the water here

  • Foam Brightness: How bright the foam should be in the waterfall

  • Opacity: Changes the opacity of the water

  • Opacity Edge Fade: Depth Fade on the opacity (when the water is near other objects)

  • Flow Speed: How fast the water flows

  • Start Fade: The strength of the opacity fade at the start of the waterfall

  • End Fade: The strength of the opacity fade at the end of the waterfall

  • Edge Fade: The strength of the opacity fade on the edges of the waterfall

  • Object Detection: Toggle to enable object detection on material

  • Object Detection Size: The distance to the nearest surface to check for object detection

  • Object Detection Strength: An overall strength multiplier for the object detection checks

  • Object Detection Smoothness: The gradient for the fade when colliding with objects

  • Actors to Ignore: The waterfall will ignore any actors defined here for any of its collision checks

• Particles:

  • Water Particle Color: Change the colour of all the particle effects here

  • Enable Top Splash: Toggles the splash particle at the top of the waterfall on and off

  • Top Splash Lifetime: The lifetime of the splash particle at the top of the waterfall

  • Enable Mist: Enable and disable the mist particle

  • Mist Lifetime: The lifetime of the mist particle

  • Enable Ground Splash: Toggles the splash particle at the bottom of the waterfall on and off

  • Ground Splash Scale Offset: Scales the splash particle at the bottom of the waterfall

  • Ground Splash X Location Offset: Offsets the location of the splash particle at the bottom of the waterfall

In versions 4.27 and prior, the particles use Cascade rather than Niagara and are only visible when simulating/playing in editor
