Using the Track View Editor

The Track View editor is the primary tool for creating and managing cinematic sequences. It is accessed from Lumberyard Editor by clicking Tools, Track View. The Track View editor consists of the following components:

Track View Editor Toolbars

  • Node browser – Tree pane of all nodes and associated tracks.

  • Curve Editor – Pane for controlling keys and their interpolation for all sequence entities.

  • Track Editor – Track timeline of all sequence tracks. Each row in the timeline corresponds to a track listed in the accompanying node browser.

  • All of the buttons in the Track View editor have descriptions appear when you hover the mouse over them.

Using Cutscene Animation Curves (Curve Editor)

The Curve Editor displays animations as function curves. Each track's curves represent an animation of a property value (such as anchor, offset, color, or any property of a UI element).

The elements of a curve

  1. Curve or spline

  2. Spline key

  3. Tangent handles


                Elements of a curve in Track View editor's Curve Editor

Select a keyframe to see the associated tangent handles and then drag the boxes at the keyframes or the ends of the tangent handles (including unify tangents and automatic tangents) to manipulate them. When moving keyframes, hold down Shift to constrain the movement to time only, and Alt to scale the selected keyframes around the play head location.

The path of the curve represents the transition of the value between the keyframes. If the value changes in a straight line between each keyframe (linear), transitions between keyframes will not be smooth. The default curve causes the value to smoothly ease in and ease out. Each key has an in tangent and an out tangent. Depending on the preferred effect, you can use the toolbar icons to switch the tangents to auto, zero, step, or linear. You can also manually drag the tangent handles.

By default, animation tracks are recorded with a smooth transition. You can use the buttons in the toolbar at the top of the Curve Editor to change how the curves behave on either side of the selected key. You can also drag spline keys to a different point in the timeline.

To zoom in or out

  • Scroll the mouse wheel

To pan the view

  • With the mouse in the Curve Editor, drag using the middle mouse button

To adjust a spline key

  1. In the Node Pane, select a track. The curves for that track appear in the Curve Editor.

  2. In the Curve Editor, select a spline key.

  3. Do one or more of the following:

    • Drag the spline key to a different point on the timeline.

    • Use the toolbar buttons to select a preset: auto, zero, step, or linear.

You can select multiple spline keys to modify at once. Once selected, you can move them all together, set their in and out tangents, and so on.

To select multiple spline keys

  • In the Curve Editor, drag a selection box over all the spline keys you want to select.

To edit multiple elements at once

  1. In the Animation Editor's node pane, select the track that contains the subtracks you want to edit.

    In the following example, the Scale track is selected. It contains the X and Y subtracks.

    
                        Select the Scale track, which contains the X and Y subtracks
  2. Drag a selection box over the spline keys you want to select.

  3. Drag spline keys to edit their position.
