Polygon Selection Tag Basic FieldsFields
The tag can be controlled by Fields. To do so, enable the Use Fields option in the Basic Properties menu.
Selection tags have one of two states: selected or unselected. The value at which an element is seen as being selected is defined by this setting. A Tolerance value of 50% means that the value must be larger than 0.5 in order to be deemed selected. If Tolerance is set to 100%, even a value of 0.1 will be deemed selected.
The Fields list can contain various position-dependent Fields. Imagine, for example, a Spherical Field that has a specific position. If the object to which the tag is assigned is deformed by a deformer/effector, for example, the position of the object points/clones, etc. will change. If the Spherical Field should affect the deformed or non-deformed element state, this is the option that should be used.
This option must be enabled if, for example, a character animated with joints (or elements of a matrix controlled by an effector) should move through the Spherical Field and the Spherical Field should take effect when the character passes through.
See, for example: Field.
