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]
