characterize is undoable, queryable, and editable.
This command is used to scan a joint hierarchy for predefined joint names or
labels. If the required joints are found, human IK effectors will be created
to control the skeleton using full-body IK.
Alternatively, you can manually create all of the components
required for fullbody IK, and use this command to hook them up.
Fullbody IK needs 3 major components: the
user input skeleton (sk), the fk skeleton on which keys are set (fk) and the
hik effectors (ik). Together fk and ik provide parameters to the fullbody IK
engine, which solves for the output and plots it onto sk. This command usage
is used internally by Maya when importing data from fbx files, but is not generally recommended.
In query mode, return type is based on queried flag.

Properties |
-placeNewPivot(-pnp)
|
|
|
|
Creates a new pivot and puts it into placement mode. Note that you will
not be able to do full body manipulation about this pivot until you have
activated it with the -activatePivot flag. A pivot behaves in all ways the
same as an effector (it IS an effector, except that it is offset from the
normal position of the effector to allow one to rotate about a different
point). A new pivot created with this flag allow you to adjust the offset
interactively before activating it.
|
|
-activatePivot(-apv)
|
|
|
|
Activates a pivot that has been properly placed. After activating this new
pivot, you will now be able to rotate and translate about this pivot.
A pivot behaves in all ways the same as an effector (it IS an
effector, except that it is offset from the normal position of the effector
to allow one to rotate about a different point.
|
|
-changePivotPlacement(-cpp)
|
|
|
|
Reverts a pivot back into pivot placement mode. A pivot that is in placement
mode will not participate in full body manipulation until it has been activated
with the -activatePivot flag.
|
|
-addAuxEffector(-aae)
|
|
|
|
Adds an auxilliary (secondary) effector to an existing effector.
|
|
-addFloorContactPlane(-afp)
|
|
|
|
Adds a floor contact plane to one of the hands or feet. With this plane,
you will be able to adjust the floor contact height. Select a hand or foot
effector and then issue the characterize command with this flag.
|
|
-pinHandFeet(-phf)
|
|
|
|
When the character is first being characterized, pin the hands and feet by default.
|
|
-type(-typ)
|
string
|
|
|
Specifies the technique used by the characterization to identify the joint
type. Valid options are "label" and "name". When "label" is used, the joints
must be labelled using the guidelines described in the Maya documentation.
When name is used, the joint names must follow the naming conventions
described in the Maya documentation. The default is "name". This flag
cannot be used in conjunction with the sourceSkeleton flag.
|
|
-posture(-pos)
|
string
|
|
|
Specifies the posture of the character. Valid options are "biped" and
"quadruped". The default is "biped".
|
|
-sourceSkeleton(-sk)
|
string
|
|
|
This flag can be used to characterize a skeleton that has not been named or
labelled according to the FBIK guidelines. It specifies the association
between the actual joint names and the expected FBIK joint names. The format
of the string is as follows: For each
joint that the user wants to involve in the solve: 1) the partial path of
the joint and 2) the name of the full body joint this represents. 1) and 2)
are to be separated by white space, and multiple entries separated by ",".
|
|
-fkSkeleton(-fk)
|
string
|
|
|
Specify the fk skeleton to be used by human IK by providing 2 pieces of
information for each joint of the FK skeleton: 1) the partial path of the
joint and 2) the name of the full body joint this represents. 1) and 2) are
to be separated by white space, and multiple entries separated by ",".
Normally, the fk control skeleton is automatically created. This
flag is for advanced users only.
|
|
-effectors(-ef)
|
string
|
|
|
Specify the effectors to be used by human IK by providing
2 pieces of information for each effector: 1) the partial path of the
effector and 2) the name of the full body effector this represents. 1) and
2) are to be separated by white space, and multiple entries separated by ",".
Normally, the effectors are automatically created. This flag is
for advanced users only.
|
|
-stancePose(-sp)
|
string
|
|
|
Specify the default stance pose to be used by human IK. The stance pose is
specified by providing 2 pieces of information for each joint involved in
the solve:
1) the partial path to the joint and 2) 9 numbers representing translation
rotation and scale.
1) and 2) are to be separated by white space, and multiple entries separated
by ",".
Normally, the stance pose is taken from the selected skeleton. This flag is
for advanced users only.
|
|
-addMissingEffectors(-ame)
|
|
|
|
This flag tells the
characterize command to look for any effectors that can be added to the
skeleton. For example, if the user has deleted some effectors or added fingers
to an existing skeleton, "characterize -e -addMissingEffectors" can be used to
restore them.
|
|
-attributeFromHIKProperty(-ahk)
|
string
|
|
|
Query for the attribute name associated with a MotionBuilder property.
|
|
-attributeFromHIKPropertyMode(-mhk)
|
string
|
|
|
Query for the attribute name associated with a MotionBuilder property mode.
|
|
-autoActivateBodyPart(-aab)
|
boolean
|
|
|
Query or change whether auto activation of character nodes representing body parts
should be enabled.
|
|
-name(-nm)
|
string
|
|
|
At characterization (FBIK creation) time, use this flag to name your FBIK character.
This will affect the name of the hikHandle node and the control rig will be put
into a namespace that matches the name of your character. If you do not specify
the character name, a default one will be used.
At the moment edit and query of the character name is not supported.
