Animating parameters
You can animate most parameters in AXEL. For example, animate material transparency, color; or the angle of a pin joint. To animate a parameter, you record keys for that parameter.
AXEL uses interpolation to determine the state of the object in between the recorded keys.
To animate a parameter:
- Turn off Play and go to the time where you want the animation to start.
- In the World Explorer, select the parameter you want to animate.
- Choose Animation > Add Animation Sequence, or turn on Record (
), or press Ctrl+K.
An animation sequence appears in the Sequencer. Notice the first key.
- Make sure Record is on, go to another time, and adjust the parameter.
- Repeat step 4 to record additional keys.
- To preview the result, drag the playhead to the start and click Play.
To animate position, rotation, or scale:
- Turn off Play and go to the time where you want the animation to start.
- Turn on a Translate (
), Scale (
), or Rotate (
), and select the object you want to animate.
- Choose Animation > Add Animation Sequence, or turn on Record (
), or press Ctrl+K.
This creates an animation sequence and a first key. If the Translate button is on, it creates a position animation. If the Rotate button is on, it creates a rotation animation, if the Scale button is on, it creates a scale animation.
- To record another key, go to another time, and drag the object in a viewport.
- To preview the result, drag the playhead to the start and click Play.
Example: Animating the scale of a sphere
- Turn off Play, turn off Record, and go to time 0.
- Select the sphere.
- Turn on the Scale button (
).
- Choose Animation > Add Animation Sequence.
An animation sequence appears in the Sequencer.
- Go to time 2 and scale the sphere.
A new key appears in the Sequencer.
- Go to time 4 and scale the sphere again to add another key.
- To preview the animation, scrub the Sequencer or go to time 0 and turn on Play.
- Continue adding keys until you are pleased with the animation and then turn off Record to avoid adding keys by mistake.
