Time-Based Animation
In Bryce, key events are tied to real-world time increments (minutes and seconds) rather than individual animation frames. This means that you can create key events at specific points in time without worrying about the number of frames in your final animation.
Bryce automatically creates all the frames necessary to move from one key event to another. If you change the frame rate, Bryce adjusts the number of the frames between key events to match the new frame rate.
For example, let's say your frame rate is set to 15 fps (frames per second) and then you set up two key events, one at 1 second and the other at 2 seconds. Bryce automatically fills in the 15 frames necessary to move from the key event at 1 second to the key event at 2 seconds. If you change the frame rate to 30 fps, Bryce will add another 15 frames between the two key events to match the new frame rate.
Animation and Motion Paths
As you change the position, of an object, Bryce creates a motion path which shows you the path the object will take as it moves from one key event to another.
An object's motion path shows you the trajectory of the object as it moves from one key event to another.
You can edit an object's motion path to adjust its trajectory throughout the course of the animation.
Refer to "Editing Motion Paths" for more on motion paths.
Animatable Properties
Each characteristic of an object or effect that can be animated is called a property. Most objects have many animatable properties. Properties like position, size and orientation are common to all objects. Other properties are specific to certain types of objects.
Lights have special properties like brightness, falloff and gels.
Skies have their own set of properties that control everything from cloud coverage to the time of day.
The properties of individual objects can change depending on the material you apply. The color, texture, and density of an object can also be animated.
Some properties can be animated directly in a specific editor. Object material properties can be animated from within the Materials Lab and terrain geometries can be edited from within the Terrain Editor.
Properties in the Sequencer
Every time you change an object's property, it appears as a key event in the animation's Sequencer. In the Sequencer, each property of an object can be viewed on a separate timeline. You can expand an object's listing to see all the transformations or changes that have been applied to its properties. If you have not performed any transformations on the object, it cannot be expanded.
Refer to "Editing Property Timelines in the Sequencer" for a complete discussion of the Sequencer.
To expand a listing in the Sequencer:
1 Make sure the Advanced Motion Lab is visible. If it's not, choose Objects menu> Advanced Motion Lab.
