This is the place for the mesh’s fundamental settings. They directly influence the way the polygons are created around the particle cloud.
Build
This option tells RealFlow whether the mesh should be generated during the simulation process or not. We do not recommend to set it to “No”, because meshing should always be a post process. There are so many settings that it would actually be impossible to create a convincing mesh on the fly simultaneously with the particle simulation.
Type
RealFlow's “Particle Mesh” provides three modes to create completely different results and looks. To get a better understanding of how these methods work, please read the introduction “Isotropic vs Anisotropic” in the particle mesh description. The first method is called “Metaballs”. Metaballs can be seen as spheres which can influence one another to create an organic-looking, smooth surface. Metaball-based fluid meshes often show thick borders and require a certain amount of filtering or correspondingly high particle counts to achieve a better quality.
...
Finally, there is “Weighted anisotropic”. This mode creates meshes with thin borders, but sometimes the fluid has a torn look. To compensate for this effect, the “Radius” parameter of the attached emitter's “Field” panel should be increased. Please use a moderate “Filter” with this option. “Weighted anisotropic” is slower than its isotropic counterpart, but this difference is almost negligible with lower numbers of particles.
Weight normalization
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.
