User Manual

A final alternative method for creating a motion path is to draw a spline shape first and then
connect a path modifier to the spline. Using any of Fusion’s spline tools, you can draw the
shape of the path and then connect the path modifier to the published spline. Once the path
modifier and the published spline are connected, you can keyframe the Displace parameter to
move an image along the path. This method is useful when you want to use a paint stroke or
mask shape as a motion path.
To use a mask shape or paint stroke as a path:
1 Draw a polygon mask or paint stroke in the shape of the path you want to use.
You do not have to close the mask shape.
An open Polyline mask shape.
2 When done drawing the shape, click the Insert and Modify button in the viewer toolbar
to leave the mask shape as an open spline.
3 At this point you can select any of the control points along the spline and press Shift-S
to make them smooth or Shift-L to make them linear.
All mask polylines have animation enabled by default, but that is usually not desirable
for a motion path. You will need to remove this keyframe animation if you are using a
mask shape.
