The mode of operation is exactly the same for each cutting plane and its related parameters. Volume maps can be neither rendered nor exported or transferred to other nodes. They are just a visual help to give you an idea how the current objects interacts with Hybrido fluids, for example when you see leaking grid fluid particles. We have prepared a detailed introduction about how to use these maps under "HyFLIP - Volumes and Distance Fields".
Isosurface
With this option you can visualize how the Hybrido fluid solver actually “sees” an interacting object. For this purpose, RealFlow takes all settings from an object's “Volume” panel into account. All changes will be displayed in real-time and you will be able to see where objects are leaking immediately. This feature will help you to adjust the interaction between the fluid and an object much faster, especially due to the fact that the “Isosurface” view can be combined with the “Slice plane [axis]” options, giving you the ability to visualize an object's signed distance field.
