This is the first of six “killer” daemons to eliminate unwanted particles. There are many cases where particles become invisible in the final camera view or leave a certain area. In most cases these particles only increase simulation time without any additional benefit for the project – especially grid fluid splash or foam particles profit from "k Volume" daemons. Sometimes there are also some particles escaping from a scene, slowing down the fluid engine significantly. It is a real necessity to remove all these kinds of unwanted particles and a "k Volume" daemon should be added to (almost) any scene. The "k Volume" daemon is easy to handle and it can be treated just like a cube object: dimensions, position and rotation are simply specified under the daemon’s "Node" window. The “Shear” option only changes the daemon's viewport representation, but does not have any influence on its functionality or scope.
Fit to object
This button fits the daemons bounding box to the dimensions of a certain object. By clicking on this button, the well-known node browser appears giving you the opportunity to select one item from the list. Please note that automatically adjusted daemons do not fit the selected object exactly and there is also a cache between the outlines of the object and "k Volume".
Fit to scene
For the calculation of the daemon’s bounding box, RealFlow takes all scene elements into consideration and you do not have to choose an individual object.
Inverse
With this option it is possible to decide where the particles will be deleted. With "No", particles will be removed outside of the volume, with "Yes", this happens outside.
