Also suitable for hovering and downwash fx over Snow, Sand, and Water.

Inside, you’ll find three unique downwash variations:

DownwashA is 10 metres wide and lasts 350 frames.

DownwashB kicks up more dust and lasts 340 frames long.

DownwashC is the largest of all, 15 metres wide with the highest dust kickup and lasts for 410 frames.

Each version is designed to fade slowly to allow for helicopter rotor slowdown when landed.

—plus three seamlessly looping versions for continuous effects each 250 frames long.

Every effect includes three Levels of Detail (LODs), giving you full control over performance and visual fidelity across projects of any scale.

What’s included:

• 18 VDB files

• 6 ready-to-use Blueprints

• 18 Heterogeneous Volume assets

Ideal for cinematics, and VFX-heavy scenes, with the lowest LOD for real-time, this pack makes it easy to add powerful environmental interaction with minimal setup.

Cinematic Rendering

For Cinematic Rendering, on the Heterogeneous Actors turn "Issue Blocking Requests" to on, and Under Lighting change "Lighting Downsample Factor" to 1.

and use:

r.HeterogeneousVolumes.OrthoGrid 1

r.HeterogeneousVolumes.OrthoGrid.MaxBottomLevelMemoryInMegabytes 512 (default 128)

r.HeterogeneousVolumes.OrthoGrid.ShadingRate 1 (default 4)

Path Tracer

To render heterogeneous volumes with the path tracer, enable the following:

• Project Settings

  • Set the Default RHI to DirectX 12.

  • Enable Support Hardware Ray Tracing.

  • Enable Path Tracing

and use the console variable:

r.PathTracing.HeterogeneousVolumes 1
