Displace - Spherical Field

The Displace category offers two kinds of displacement models to push particles along. The one discussed here is Spherical Field, which is a displacement field in the form of a sphere. The sphere can either push particles outward or suck them in. Spherical Field is not a force field. The field's effect is instant and does not leave a trace once the field is removed.

Strength

Strength is the directional displacement amount with which the field pushes particles around. Positive values create a field that pushes particles outward. Negative values mean particles get sucked inward.

Radius

Radius allows you to adjust the Spherical Field's size uniformly.

Sphere Position

This control lets you set the Spherical Field's position along the x, y, and z axes.

Scale X, Y and Z

This control sets the size of the Spherical Field on a specific axis. Making the value smaller decreases the size of the field on that axis.

Rotate X, Y and Z

These controls allow you to rotate the spherical field on the x, y, or z axes. This works best when x, y, and z scale values are different.

Feather

Feather sets the Softness of the Spherical Field's edges. Higher values make a softer field.

Visualize Fields Checkbox

When this checkbox is turned on, a visual representation of the field is displayed. The x plane is in red, the y plane is in green, and the z plane is in blue. This option is turned off by default but becomes visible in the Designer when selecting the Fields block regardless of that field's strength.
