Edit field attributes
The type of field and its attributes specify the kind of effect it has. You can set
the field attributes before you create the field, or you can create a default field
and set the attributes after creation.
To set field attributes before creating the field
- From the or menu set, select > fieldname >
to display the options window for the field.
- Set the attributes.
To enter a value that exceeds a default slider range, type the value in the text box.
- Click the to create the field.
To edit field attributes after creating the field
- Select the field you want to edit.
TIP:
You can select the particle object connected to the field and the displays a tab for the field.
- Do one of the following:
- Use the or to set the attributes. The attributes are described in the field descriptions in
this chapter.
- Use the workspace manipulators to edit commonly used field attributes (see Set field attributes with workspace manipulators).
TIP:
You can animate field effects by setting the field attribute values with keys or expressions.
To turn off the effect of a field at some frame, you can key the value of its attribute to 0. Make sure the key are if you want the to change abruptly to 0 rather than with a gradual interpolation.
Set and
In the and the option window, attributes not applicable to a volume shape are dimmed. However, the
does not support dimming. We recommend you use the instead of the to edit volume field attributes until you become familiar with the attributes that
apply to each volume shape. Some Volume Control Attributes, including, Volume Trapping, Axial Magnitude, and Curve Radius attributes are only available in the Attribute Editor.
To set and
- Select the field and display the .
TIP:
You can select the particle object connected to the field and the displays a tab for the field.
- Enter values for the volume shape attributes.
See Volume Control Attributes and Volume Speed Attributes.
Tips on using volume fields
- The action of a vortex field is still controlled by its attribute, even for a field. If you want a circular motion around the section axis of the torus, use the
field (see Work with volume axis fields).
- You cannot deform or tweak the field volume. You are restricted to the volume types
we provide—you can’t use general volumes.
- The field attribute still applies with volumes.
- There are no manipulators for the field attributes.
- You can trap objects inside volume fields using volume trapping attributes. See Volume Trapping.
- You can use the to set field along the axis of a volume shape field or volume axis curve. See Axial Magnitude.
- When working with volume axis curves, you can use the ramp to scale curve along the curve’s axis. See Curve Radius.
