The interactive controls for the native Outer Glow live effect consist of two arms extending from the center circle, along with one dropdown menu and a color chip:
Stylism Outer Glow Controls
The annotated blending mode dropdown menu allows you to select the outer glow blending mode, from among Illustrator’s standard 16 blending modes.
The blur slider thumb control may be dragged along the blur arm to change the outer glow’s blur radius, between 0 and 144 pt. The value increases away from the center circle. When the cursor is hovering over the control or dragging it, the current blur radius is displayed. The blur slider can also be clicked anywhere along its length to move the blur thumb immediately to that position. While dragging the blur slider, in addition to the common keypresses (see Stylism Annotated Controls and Common Drag Keypresses), the following keypresses can be used:
Shift: Constrains the blur radius to integer values.
Doubleclicking
the control brings up a dialog which allows you to enter the blur radius numerically.
The opacity slider thumb control may be dragged along the opacity arm to change the outer glow’s opacity, between 0% and 100%. The value increases away from the center circle. When the cursor is hovering over the control or dragging it, the current opacity is displayed. The opacity slider can also be clicked anywhere along its length to move the opacity thumb immediately to that position. While dragging the opacity slider, in addition to the common keypresses (see Stylism Annotated Controls and Common Drag Keypresses), the following keypresses can be used:
Shift: Constrains the opacity to steps of 10%.
The color control shows the color of the outer glow. To specify a new color, click the square to bring up the standard color picker.
