Shape Layers: Animating the Slider Graphs

This section demonstrates a critical workflow in professional motion graphics: converting imported Illustrator vectors into native After Effects shape layers. While we've covered basic conversion techniques, this exercise reveals how to manage the complexity that often emerges from detailed vector artwork—a common challenge when working with client-provided assets or intricate UI designs.

  1. With the HUD—Your Name.aep file open, click on the Graph—Sliders layer to select it and:
    • Press Cmd–Shift–C (Mac) or CTRL–Shift–C (Windows).
    • Change the name to Graph—Sliders—Animated
    • Confirm the Open New Composition switch is enabled.
    • Click OK.
  2. CTRL–click (Mac) or Right–click (Windows) on the layer and choose Create > Create Shapes from Vector Layer and then:
    • Press Return (Mac) or Enter (Windows) and rename it Slider 01
    • Press Return (Mac) or Enter (Windows) again or click on any empty area of the timeline to finalize the change.

  3. Click the reveal arrow for Slider 01 and then click the reveal arrow for Contents.

    This reveals 116 separate groups—a perfect example of how detailed vector artwork can create unwieldy shape layer hierarchies. Each diagonal line segment and circular element has been converted into its own group, which is typical when working with complex Illustrator files that contain numerous anchor points and path segments.

  4. Click on the label color for the Slider 01 layer and change it to Yellow and then:
    • Click on Group 1 to see which shape highlights.
    • Repeat this selection process for Group 3 and Group 10.

    Notice the logical creation order? After Effects processes vector elements systematically during conversion. By methodically clicking through different groups, we can map the relationship between groups and visual elements. This detective work is essential for managing complex shape layers efficiently—we've already done this analysis for you in this exercise.

  5. Click on Group 30:
    • Hold Shift
    • Click on Group 116 to select every group in-between.
    • Press Delete (Mac) or Backspace (Windows) to delete all the highlighted shapes.
  6. Click on Group 2:
    • Hold Shift
    • Click on Group 29 to select every group in-between.
    • CTRL–click (Mac) or Right–click (Windows) on any of the highlighted shapes and choose Group Shapes.
    • Press Return (Mac) or Enter (Windows) and rename the new group Other Assets.
    • Press Return (Mac) or Enter (Windows) again or click on any empty area of the Timeline to finalize the change.
  7. Click on Group 1:
    • Press Return (Mac) or Enter (Windows) and rename the new group Ball.
  8. Click the reveal arrow right arrow menu for the Ball shape and then:
    • Press the reveal arrow for Transform: Ball.

  9. Change Scale to 125

  10. Hold Option (Mac) or ALT (Windows) and click on the stopwatch stopwatch for Position.

  11. Add the following expression code to create organic movement:

    myWig = wiggle(3,30);

    [myWig[0], value[1]];

    Click the reveal arrow for the layer to hide the visible properties.

    This expression creates horizontal oscillation while maintaining the original Y position—perfect for simulating data fluctuation in technical interfaces. Click anywhere outside the text field to finalize the expression.

  12. Press Spacebar to preview the Timeline.
    • Press Spacebar again at any time to stop the preview.
  13. Click on Slider 01 and press Cmd–D (Mac) or CTRL–D (Windows) to duplicate the layer and:
    • Hold Shift and press the Up Arrow on the keyboard until the new layer is above the first slider.
    • Repeat this step until you have 4 sliders

    Position the topmost slider at the composition's upper boundary to establish proper hierarchy.

  14. Select all 4 sliders and choose Window > Align and:
    • Click the Distribute Vertically distribute vertically button.
    • Choose Window > Workspace > Reset "Standard" to Saved layout
  15. Press Spacebar to preview the Timeline.
    • Press Spacebar again at any time to stop the preview.

    Despite identical initial positioning, the wiggle expression ensures unique horizontal movement for each ball, creating the impression of independent data streams—a sophisticated touch that elevates the realism of your interface design.

  16. Press Cmd–K (Mac) or CTRL–K (Windows) or choose Composition > Composition Settings and:
    • Confirm the Lock Aspect Ratio switch is enabled.
    • Change the Width to 235
    • Click OK to close the dialog.

  17. Close the Graph—Sliders—Animated composition and return to the Shape Animation—HUD composition to observe how the nested composition integrates into the larger design system.

  18. Press Spacebar to preview the Timeline.
    • Press Spacebar again at any time to stop the preview.

  19. Save the project by choosing File > Save or pressing Cmd–S (Mac) or CTRL–S (Windows).

Shape Animation: Making a Layer Follow a Custom Motion Path

While simple animations can rely on basic curves and manual keyframe adjustments, professional motion graphics often demand precise path-following behavior. The Create Nulls from Paths feature—a powerful but underutilized tool in After Effects—transforms any vector path into a controllable motion system. This technique proves invaluable for complex UI animations, logo reveals, and any scenario where elements must travel along specific trajectories with frame-perfect accuracy.

Create Nulls from Paths Feature

This powerful After Effects panel allows you to create null objects that follow or control paths, essential for complex animation tasks beyond simple curves and arcs.

Custom Motion Path Setup

1

Identify Source Path

Locate the specific group that aligns with your marker layer - in this case Group 6 from the Line Bundle

2

Create Path Copy

Copy the group to a new shape layer and reset Transform Position to 0,0 for proper alignment

3

Generate Null Controller

Use Create Nulls From Path panel to trace the path and create a controller null object

4

Parent and Sync

Parent the marker to the controller and match keyframe timing with Easy Ease In for synchronized movement

    • Double–click on HUD—Custom Motion Paths.aep to open it.

  3. Choose File > Save As > Save As and:

    • Name the file Your Name—HUD.aep and
    • Save it into Desktop > Class Files > After Effects Advanced Class> Shape Animation.
  1. In the Shape Animation—HUD comp, select the [Line Bundle—Animated] layer and:
    • Press Return (Mac) or Enter (Windows) and rename the layer Circuitry Animation.
    • Press Return (Mac) or Enter (Windows) again to finalize the name change.

  2. Double–click the Circuitry Animation comp layer to open it. If any layers are expanded, click on them and press CTRL ~ to collapse their properties for better visibility.

  3. Move the playhead to 02;00 on the Timeline (positioned after the line animations complete) and click on the eye eye icon icon for the Marker—Outline layer to reveal it.

    Our objective is to identify which circuit line the marker should follow, then create a duplicate path specifically for motion control—a common workflow when separating visual elements from their animation drivers.

  4. Click the reveal arrow right arrow menu next to the Line Bundle Outlines layer and:

    • Click on the various groups until you locate the one that aligns with the Marker—Outline layer. (Hint: it's Group 6)
  5. With Group 6 selected:
    • Choose Edit > Copy or press Cmd–C (Mac) or CTRL–C (Windows) to copy the shape.
    • Press CTRL ~ to hide the layer properties.
    • Choose Layer > New > Shape Layer.
    • Choose Edit > Paste or press Cmd–V (Mac) or CTRL–V (Windows).
  6. With the new Shape Layer 1 selected press Return (Mac) or Enter (Windows) and rename the layer Outline—Path
    • Press Return (Mac) or Enter (Windows) again to finalize the name change.
  7. Click the reveal arrow right arrow menu for Outline—Path and then:
    • Click the reveal arrow for Contents.
    • Click the reveal arrow for Group 6
    • Click the reveal arrow for Transform: Group 6

  8. Locate the Position property inside Transform: Group 6 and set it to 0,0

  9. Activate the Selection Tool by pressing V on the keyboard and drag the Outline—Path layer to align it precisely with the source path on Line Bundle Outlines.

    Use zooming and keyboard arrow keys for pixel-perfect alignment—precision here directly affects the smoothness of your final animation.

  10. With Outline—Path selected click the reveal arrow right arrow menu next to Path 1 to reveal the Path property.

  11. Choose Window > Create Nulls From Path.jsx from the bottom section of the Window menu.

    Reposition the Create Nulls From Paths panel to maintain visibility of the Comp panel—efficient panel management is crucial for complex workflows.

  12. Click the Trace Path button. After Effects generates a null object layer with position data dynamically linked to your selected path's geometry through sophisticated expression scripting.

    • Close the Create Nulls From Paths panel.

    Critical note: Never delete the source path after tracing. The null object's connection to the original path depends on live expression references—removing the source will break the entire motion system.

  13. Click on the Trace Outline—Path: Path 1 [1.1] layer and:
    • Press Return (Mac) or Enter (Windows) and rename it Controller—Outline—Path.
    • Return (Mac) or Enter (Windows) again to finalize the name change.
  14. Select the Controller—Outline—Path layer and press E to see its effects and:
    • Click the reveal triangle right arrow menu next to Trace Path.
    • Change the Loop property to Off.
    • Move the playhead to the position of the second Progress keyframe.

    Observe how the null object precisely matches the Marker—Outline position—this demonstrates the accuracy of the path-tracing system.

  15. Turn off the visibility of the Outline—Path layer by clicking off its eye eye icon switch.

    The Outline—Path layer has served its purpose as a tracing target and can now be hidden to reduce visual clutter.

  16. Use Marker—Outline's parent pick whip pick whip icon to make it the child of Controller—Outline—Path.

  17. Press Spacebar to preview the Timeline.

    • Press Spacebar again at any time to stop the preview.

    Notice the marker follows the line's path but with timing discrepancies—this occurs because the Trim Path effect includes easing that we haven't yet matched in our motion controller.

  18. Click on the Line Bundle Outlines layer and press U to reveal its keyframes. Note the Easy Ease In applied to the second keyframe.

  19. On the Controller—Outline—Path layer CTRL–click (Mac) or Right–click (Windows) on the second keyframe and choose Keyframe Assistant > Easy Ease In.

  20. Hide the properties of both the Controller—Outline—Path and Line Bundle Outlines layers.

  21. Save the project by choosing File > Save or pressing Cmd–S (Mac) or CTRL–S (Windows).

    For additional practice with this essential technique, apply the same path-following workflow to the Marker—Solid layer or experiment with your own custom paths.

Critical Path Dependency

Never delete the source path after tracing. The connection between null object and traced path relies on complex expressions that will fail if the source is removed.
