A Hybrido fluid's displacement can be seen as an additional layer on top of the main body of water. This layer adds small waves and ripples to the surface and provides extra realism. In order to use this feature with a simulation, it has to be activated manually under the Hybrido domain's “Ocean Statistical Spectrum” panel. The surface structure is exported as a sequence of TIFF images. When loaded to the “RealFlow Hybrido Mesh” plugin the height information is used to displace the mesh's vertices. The bitmaps can be processed with the → “RealFlow “RealFlow RenderKit Displacement” Displacement” tool as well, and mapped to any other geometry.
If your core fluid simulation has been simulated without displacement, this parameter set can be ignored. Please bear in mind that this option is very RAM-intensive and creates very large meshes – several million polygons per frames are absolutely normal.
For more information about attenuation and normalization, please read the → introduction to these features.

This option uses the Hybrido Domain's “Quality” parameter from the “Displacement” channel to control the resolution at the mesh's edges. An example: With a “Quality” value of 512, the mesh's edges are subdivided until there are 512 triangles at each sidedomain's projection plane is used to compute the edge length. The result is its side length divided by 512. For this process, the domain's projection plane is used. When set to “No” the “@ edge length” parameter is unlocked where you can define the edge length manually.
@ edge length
This parameter is only accessible when “Auto edge length” is disabled (“No”). The value given here will be used by the HyMesh engine to define the length of the mesh's border triangles. The final number of edge triangles, on the other hand, is then calculated from this length. The value is measured in metres [m]
