With this daemon it is possible to create, customize, and fine-tune crown splashes. This kind of splash can normally be observed when a drop of water is falling onto a water surface. First you will see a ring rising. Due to the fluid's surface tension, the “edges” are contracting and forming small drops. These effects create the typical crown-shaped look.
A few tips and notes:
- Create a sufficient amount of initial particles. The more particles, the better the splash.
- If the splash looks torn increase “Crown width”. This helps to attract more particles and make the splash “thicker”.
- The "Crown" daemon has an internal hole-filling ("Sheeter") function that prevents the fluid from being torn.
- Simulations where the "Crown" daemon is used cannot be → retimed.
Strength
This parameter defines the force that will be acting on the particles:
- Higher forces lead to stronger acceleration and a quickly growing crown.
- The final height of the crown also depends on “Acting time” and external forces, e.g. → “Gravity”.
- If you have multiple “Crown” daemons the forces will be summed up in overlapping areas.
- With downscaled emitters it is very likely that you have to increase “Strength”.
Creation time
Here you can specify the point in time when the daemon will start to form the crown splash. “Creation time” is measured in seconds.
Acting time
The value is the time in seconds during which the daemon's force (“Strength”) is acting on the particles. With higher values, the crown will be higher as well. Please be aware that this parameter is very sensitive.
Surface tension
This property describes a fluid's tendency to form drops. With high values, you often see a contraction, but also a coherent fluid with thicker borders. This parameter has been added for your convenience, but you can also use the emitter's "Surface tension" or the appropriate → daemon.
Spikes count
Spikes are accelerated faster than the rest of the fluid and this results in longer tendrils. The number of spikes is defined with this parameter. The individual height of each spike can determined in the daemon's “EDIT” mode: select a spike's corresponding point, hit W, and move it along the arrow's direction.
Crown width
In order to get a “thicker” splash, please increase the parameter's value. The value is measured in metres.
EDIT
The daemon's editing features allow you to create a wide variety of shapes, and you are not restricted to regular splashes with perfectly aligned tendrils. When the daemon is in edit mode you will see a yellow frame around the viewport. Then you have access to the editing points and spline handles. Please press the W key to move the points. Rotation (E) and scaling (W) are available for multiple selections of points.
- By shifting the viewport gizmo's editing points it is possible to create a wide variety of cross sections.
- Bottom and top can be edited and deformed separately to control the splash's width and shape. These editing points provide spline handles for changing the crown's curvature. The splash's edge will then follow this line.
- The “displaced” editing points are used to change the height of the tendrils – their number can be defined under “Spikes count”.
- Multi-selection of editing points is possible.
- The number of crown points (4 for the bottom, 4 for the top) is fixed and cannot be changed.
