Displacement, also known as ocean statistical spectrum, is a layer of small waves and ripples that is added to a → HyFLIP fluid surface to enhance realism. The displacement itself is invisible and can only be seen in conjunction with a mesh.
- Create a → basic HyFLIP scene, for example with the “Open Domain” tool.
- Add some turbulence by moving an → animated object through the fluid.
- Simulate.

A Maxwell Render snapshot of the tutorial's result. Here a → "Waterline" emitter has been added. The particles have been snapped to the mesh with the → "Snap Foam Particles" tool. Furthermore, the amount of waterline particles has been increased with the → "MultiPoint" option:
The Base Mesh
Before we proceed, it is important to set the (already simulated) domain to → “cache”:
- Click on the domain node's small green rocket.
- The yellow colour indicates the cache mode.
- Move the domain's viewport icon (plane with four boxes - here in red) to the upper third of the fluid as shown below.
