A Rig is a set of components that make possible creating character animations. A rig is, in essence, a virtual 3d skeleton made up of controllers that enable - or simplify - working with character poses.
Every character in Cascadeur always includes a rig. An object without a rig can still be animated, but possibilities for animating it are much more limited. Also, physics tools such as Ballistic Trajectories can only be applied to rigged characters.
No animation can be created without defining several key poses. This page lists tools available for editing character poses, complete with links to more in-depth articles.
A rig can include following types of elemets:
Controllers are the most important elements of the character rig. By adjusting positions of these controllers, user can move body parts of a character, thus changing the pose.
Controllers are separated into several types, each suited best for a particular task. To create your animations fast and efficiently, it is essential to use different types of controllers. This can be done by switching between Edit Modes described in the dedicated chapter.
