Object Properties
Null
If this option is enabled, the bone becomes a null bone. You can use this null bone as a parent bone
— in other words, as a parent axis system.
Smart Bone
Enable the Smart Bone option to apply a new bone algorithm. This algorithm is compatible with other
3D software and is also much faster. Once the option is enabled, a second option, Absolute Vertex
Map, becomes available.
If Smart Bone is disabled, the weighting of the bones is calculated using the function chosen (such as
1/r^2) and the result is multiplied by the default parameters. This corresponds approximately to the
standard bone algorithm.
Smart Bone enabled is a special mode, primarily meant for the importer lters such as FBX. The
weighting for each bone and each point is determined directly by the import plugin. Additionally, the
weighting of the bones can be dened directly by a vertex map or Claude Bonet map without having to
take other bone parameters into account. In previous versions of CINEMA 4D, these maps were added
to the remaining bone parameters. If Absolute Vertex Map is enabled, all other bone parameters will
be hidden apart from Null and the maps alone will control the entire weighting.
Length
Here you can enter the length of the bone. The length extends from the bone’s origin to the orange
handle. When a bone is disabled, you can scale the length of the bone by dragging the orange handle
at the end. When the bone is active, you cannot scale the bone using the orange handle.
