Advanced Controls
3D Stroke has the following Advanced controls:
Adjust Step
The stroke is made up of a number of filled circles. This setting adjusts the step length between the circles. The step is calculated using the stroke Thickness and Feather settings, and the value you set here is the percent of the calculated step length that will actually be used. This setting should normally stay at 100, but in special situations it can be altered to produce a better result. For example, if you encounter a situation when the circles of the stroke begin to appear, try decreasing this value a little.

Step normal | Step high

Exact Step Match
Checking this box will make 3D Stroke calculate the length of the stroke and then try and find a step size so that the last circle is drawn exactly on the endpoint of the path. This is will remove endpoint flickering that can sometimes appear with animated paths.

Internal Opacity
This control sets the opacity of the circle stamp used to draw the stroke. Try lowering this a lot for a more volumetric or defocused feel. It can also be used to increase feathering if set to values between 85 and 100.

Internal Opacity = 100 | Internal Opacity = 5

Low Alpha Sat Boost
This will boost saturation in areas of low alpha. In order for this to have any effect, the Color parameter should have a desaturated color and either Feather has to be close to 100 or Internal Opacity must be low.

Sat Boost = 0 | Sat Boost = 100

Low Alpha Hue Rotation
This control will change the hue in areas of low alpha. In order for this to have any effect, either Feather has to be close to 100 or Internal Opacity must be low.

Hue Rotation = 0 | Hue Rotation = -100

Hi Alpha Bright Boost
This will boost brightness in areas of high alpha. This setting looks best if either Feather is close to 100 or Internal Opacity is low.

Hue Rotation = 0 | Hue Rotation = -100

Animated Path Controls
Use Layer Time when checked, paths animate normally. When unchecked, the paths do not animate unless the Path Time below is animated.

Path Time sets the time for the path. This is useful for example when you have an animated path that takes on a number of shapes and you wish to switch/morph between them freely.
