HYM - Mesh

This is the place for the mesh’s fundamental settings. They influence the way the polygons are created around the particle cloud directly and determine the mesh's quality.

Weight normalization

A normalization step produces better results in areas where particles are clustering. When this option is enabled the mesh polygons will match the underlying particle cloud much better, but at the cost of increasing creation times. By default, this parameter is set to “No” in order to speed up the meshing process.

Auto polygon size

RealFlow’s “Particle Mesh” engine automatically adjusts the polygon size to get the best balance between quality and number of faces. You can activate/deactivate this feature by simply switching to “Yes” or “No”. With “No”, the “Polygon size” field is unlocked. 

@ polygon size

Here you can enter a custom value for the mesh’s polygon size. Smaller values lead to larger mesh files, but also more detail. Lower “@ polygon size” values take longer to calculate and need more resources. Please note that “@ polygon size” is not responsible for the rounded look of a fluid’s borders. If you want to avoid rounded borders, filters and “Radius” settings are of much higher importance. A sufficient amount of particles is also needed. Finally, the look of a mesh strongly depends on your scene scale.

Please read the “How to Adjust the Mesh's Polygon Size” chapter for further information.

Auto particle radius

“Hybrido Meshes” are created exclusively from the core fluid's particles and these particles have a certain radius. With “Auto particle radius” set to “Yes”, the mesh engine will automatically determine the radius and adjust it accordingly. “No” unlocks the following parameter where you can use a custom radius.

@ particle radius

If you are not happy with the automatically defined radius, set “Auto particle radius” to “No” and enter a value of your choice here. Please bear in mind that very large values can drastically increase mesh creation time.
