An animation layer’s state determines whether it will receive keyframes and whether its information displays in other windows and editors. Animation layers can be described as being in the following states:
- Active: A layer is active if it is going to receive keys. Active layers display in the Animation Layer Editor with a green dot
next to the layer name. Multiple layers can be active at the same time. - Affected: A layer is affected if it contains attributes of the currently selected objects, but it is not active. Affected layers display in the Animation Layer Editor with a red dot
next to the layer name. - Selected: A layer is selected if it is highlighted in the Animation Layer Editor. Depending on the keying mode you have chosen, selected layers are not necessarily active.
