A rig is made up of several components that make character animation possible.
A character with elements of the rig visualized (the rig is shown in the Point Controller mode)
An object without a rig can still be animated, but possibilities for its animation are limited. Also, Cascadeur needs a rig to calculate physically correct movements. So, physics tools such as Ballistic Trajectories can only be applied to rigged characters.
Controllers are the most important elements of the rig. By manipulating controllers, users can move body parts of a character, changing the pose. There are several types of controllers, each suited best for a particular task, and they are split into 2 categories:
Point Controllers (3 types)
Other elements include:
In the already rigged model, you can access these rig elements by switching between Edit Modes.
