Keys and interpolation frames

There are two different types of frames.

Keyframes or keys are frames in which the character's poses and positions are saved.
Keys are marked dark blue on the timeline.

Interpolation frames are frames in which intermediate poses between the keys are automatically calculated.

In Cascader there are several different types of interpolation, which are marked on the timeline with different colors.
Each type of interpolation will be explained in more detail in the following tutorials.

Restricting work area

The first and last frames of the animation are displayed under the timeline. When there are a lot of frames it is convenient to limit the visible area of the timeline to work with.

  • Double-click on the number on the right of the slider and type in a higher number of frames. For example, 80.
  • Move the edges of the slider to limit the visible area of the timeline.
  • Move the slider itself.
  • Click on the blue buttons on the edges of the slider to quickly expand the workspace to the first and last keyframes
