Simple Tab

The Simple Tab is a simplified version of the tool with less options to generate a waterfall quickly.

Buttons

• Generate Paths: Simulate particle paths to act as a guide or generating the waterfall meshes.

• Clear Paths: Delete all of the simulated paths. Note: This also resets the dynamic meshes and FX.

• Generate Meshes: Generate the dynamic mesh and material data for the waterfall.

• Clear Meshes: Clear all of the dynamic mesh and material data.

• Generate VFX: Create the global Niagara Systems and add the waterfall data to the particles.

• Bake to Static Mesh: Generate a Static Mesh asset from the dynamic meshes and assign it to the Static Mesh component of the waterall.

Properties

• Path Settings

  • Select Top Spline Points: Select spline points in Top Spline. Note: This is hidden in 5.4 because spline selection is broken in 5.4.

  • Num Paths: The number of paths to generate along the spline.

  • Spawn Jitter Range: Affects the initial direction of the path by adding a randomised jitter to the yaw in this range.

  • Path Spawn Range: If more than one path is required to spawn, this will confine the spawning to a range from the end. Eg, If the spline distance is 100 and the PathSpawnRange is set to (0.2, 0.8), then the paths will only spawn between distances 20-80 and none will spawn on the distance < 20 or > 80.

  • Gravity: Particle simulation gravity.

  • Num Spline Points: If on, after the path is generated, it will resample the path to exactly this many spline points.

  • Kill Plane Location: The X-Y values are purely cosmetic. The Z value affects where the waterfall paths will end.

  • Seed: Random seed for the generation of the waterfall.

  • Ignore Actors: Actors to ignore for collision detection and physics.

• Mesh Generation Settings

  • Single: Should the Single mesh be generated?

  • Paths: Should the Per Path meshes be generated?

  • Splash: Should the Splash mesh be generated?

  • Planes: Should the Plane meshes be generated?

• SFX

  • Top SFX: The audio asset to be played at the top of the waterfall.

  • Middle SFX: The audio asset to be played at the middle of the waterfall.

  • Bottom SFX: The audio asset to be played at the bottom of the waterfall.

• VFX Settings

  • Top VFX: Should the top VFX be generated?

  • Middle VFX: Should the middle VFX be generated?

  • Bottom VFX: Should the bottom VFX be generated?
