Water

Blueprint AI authors UWaterWavesAsset assets — the standalone, reusable wave sources a water body samples to shape its surface (the water bodies themselves are actors you place in a level). Each asset wraps a Gerstner wave generator whose parameters — wave count, dominant wind angle, amplitude and wavelength ranges, steepness — define how the surface moves.

Creating and configuring

Create a water waves asset called WW_Ocean in /Game/Water Set WW_Ocean’s NumWaves to 64 and its WindAngleDeg to 45 Set WW_Ocean’s MinAmplitude to 8 and MaxAmplitude to 120 Describe the water waves asset WW_Ocean

A new asset is created with a default Gerstner wave source, so it is immediately valid. Every wave-parameter edit re-runs the wave recompute, so the describe op’s derived wave_count and max_wave_height reflect the new settings right away.

Tip

The settable parameters are the wave generator’s own fields — NumWaves, WindAngleDeg, MinWavelength, MaxWavelength, MinAmplitude, MaxAmplitude, Seed. Describe the asset first to see the generator type and its current values.
