This node chain two bounded actions after each other.
- Relative - If enabled, the second action will be superimposed over the
last frame evaluation of the first action. The superposition is computed as
an addition except for scale channels which are computed as a multiplication.
For instance, if the first action represents the position of an object and
the object position was at some point P in the last frame, the second action
will start from this point P relative to the world origin.
- A - The first action.
- A - The second action.
- Chained Action - The output chained action.
