The joint cluster command adds high-level controls to manage the cluster percentage values on a bound skin around a joint. JointClusters are one way to create smooth bending behaviour on skin when joints rotate. . a —- aboveBound . ____________a_________ . a . Joint1 a Joint2 . _____________a_______ . a b — belowBound . a b . b . b . b . b Joint3 CVs/vertices between Joint1 and aaaaa (aboveBound) receive only translation/rotation/scale from Joint1. CVs vertices between aaaa and bbbb transition between translation/rotatation/scale from Joint1 and Joint2. CV2 beyand bbbbb (below bound) receive only translation/ rotation scale from Joint3.
Flags:
Long Name / Short Name | Argument Types | Properties | |
---|---|---|---|
aboveBound / ab | float | ![]() ![]() ![]() |
|
Specifies the where the drop-off begins in the direction of the bone above the joint. A value of 100 indicates the entire length of the bone. The default value is 10. |
|||
aboveCluster / ac | bool | ![]() |
|
|
|||
aboveDropoffType / adt | unicode | ![]() ![]() ![]() |
|
|
|||
aboveValue / av | float | ![]() ![]() ![]() |
|
Specifies the drop-off percentage of the joint cluster in the direction of the bone above the cluster. A value of 100 indicates the entire length of the bone. The default value is 50. |

belowBound / bb | float | ![]() ![]() ![]() |
|
|
|||
belowCluster / bc | bool | ![]() |
|
|
|||
belowDropoffType / bdt | unicode | ![]() ![]() ![]() |
|
Specifies the type of type of percentage drop-off in the direction of the bone below this joint. Valid values are linear, exponential, sineand none. Default is linear. |
|||
belowValue / bv | float | ![]() ![]() ![]() |
|
Specifies the drop-off percentage of the joint cluster in the direction of the joint below the cluster. A value of 100 indicates the entire length of the bone. The default value is 50. |

Derived from mel command maya.cmds.jointCluster
Example:
import pymel.core as pm
# To add a joint cluster to a rigidly bound skin.
# Note the skin should be at bind pose when the cluster is added.
#
pm.jointCluster( j='joint2', ab=20, bb=20 )
