VDB Ocean Waves & Tsunami Pack

The VDB Ocean Waves & Tsunami Pack collects simulated water effects built for high-end games and film work. It brings together ocean waves, beach waves, whirlpools, and a tsunami wave, delivered as VDB and Geometry Cache assets within Unreal Engine. The focus is on cinematic-quality water that can be dropped into a scene and played back, rather than real-time simulated fluid that reacts to its surroundings.

From VDB Cache to Unreal Engine Placement

This resource imports pre-baked simulations into Unreal Engine through two formats. VDB files carry the volumetric fluid data for splashes and aerated water, while each effect is also paired with an Alembic-based layer that represents the foamless water body beneath the splash. The Alembic layer plays back as a geometry cache, giving artists a solid-looking water surface that sits underneath the more diffuse VDB foam and spray.

The pack is explicit about what these assets are and what they are not. They are VDB and Geometry Caches of simulations. They are not Niagara systems or other real-time particle effects. This distinction matters for scene setup. The waves and splashes will follow their baked playback paths rather than sampling scene geometry or reacting to moving colliders. Planners should treat each effect as a performant, high-detail cinematic playback layer rather than a living simulation response.

Ocean Waves, Beach Waves, and Whirlpools

The three core surface effects cover distinct water behaviors. Ocean waves provide open-water motion suited to large sea surfaces and establishing shots. Beach waves handle the curl and crash that occurs where water meets the shoreline, useful for moments of impact and surf transitions. Whirlpools add rotational turbulence, giving artists a pre-simulated option for dangerous or destabilized water scenarios without authoring spinning fluid dynamics from scratch.

Each of these comes with the dual-layer treatment mentioned above. The Alembic layer provides the underlying water volume, while the VDB component handles the lighter, fractured splash and foam detail that sits above and around that volume. This separation lets scenes lean on the Alembic body for silhouette and the VDB for atmospheric breakup.

Tsunami Wave with Adjustable Playback Speed

The pack also contains one tsunami wave. This effect is notable because its wave speed is adjustable. Changing the playback speed of the tsunami lets artists tune the arrival timing of the wave to match shot framing or gameplay cinematics without re-simulating the fluid.

Instructions and supporting material are provided specifically for this asset, including guidance on how to change the tsunami wave speed. Separate demonstration videos are referenced for broader setup and quality topics: a Showcase Video for general presentation, a guide on triggering the Ocean Splash Blueprint effect, and another on improving VDB rendering quality. These supporting videos sit alongside the pack as practical references for implementation and visual tuning.

Engine Scalability and Console Tuning

Because the effects rely on Unreal Engine's heterogeneous volume rendering for VDB display, a specific scalability issue is called out. In some engine versions, VDBs can disappear after changing scalability settings. When that happens, the console command r.HeterogeneousVolumes 1 restores them.

Visible distance is another tunable parameter. By default, VDB volumes may cut off or drop out at longer view distances, which can break large coastal or ocean establishing shots. The command r.HeterogeneousVolumes.MaxTraceDistance 200000 raises that visible distance, and the pack notes that the value can be adjusted as needed for scene scale.

What This Pack Is Set Up to Handle

The package targets AAA-quality games and movies. Its workflow assumes the artist understands they are importing and triggering baked simulation data, not authoring responsive fluid. The pairing of VDB splashes with Alembic water bodies, the adjustable tsunami, and the documentation around engine console fixes all point to a resource intended for cinematic sequence building where the look of the water matters more than its runtime physics.

For projects that can work within cached playback rather than live simulation, the combined VDB and Alembic approach offers a way to get detailed ocean, beach, and whirlpool motion into Unreal Engine scenes without running those computations frame by frame.
