Constraint Method
Determines the type of links used for this dynamic constraint. Select one of the following from the drop-down list:
- Weld
-
Links lock vertices together so that they cannot be stretched.
- Spring
-
Links recover their original state when released after being compressed or stretched (default).
- Rubber Band
-
Links recover their original state when released after being stretched, but do nothing when compressed.
Constraint Relation
Determines how constrained objects are related to one another and related to the dynamic constraint. Select one of the following from the drop-down list:
- Object to Constraint
-
Relates the input components of constrained objects to the dynamic constraint node position. This means that constrained objects are affected by transform and positioning changes to the dynamic constraint (default).
- Object to Object
-
Relates the constrained objects to one another, and ignores the dynamic constraints position and transformations.
Component Relation
Determines how component nodes (nClothShape nodes, nParticleShape nodes, or nRigidShape nodes) are related to one another. A component is a member of this dynamic constraint, each member represents a subset of elements for an object (a group of triangles, or points, for example). Select one of the following from the drop-down list:
- All to First
-
Relates all components to the first component that belongs to this dynamic constraint (default).
- All to All
-
Relates all components to all other components that belong to this dynamic constraint.
- Chain
-
Relates components in series, with each component related to the next component that belongs to this dynamic constraint.
- Display Connections
-
When on, displays dynamic constraint links in the scene view. Display Connections is on by default.
Connection Method
Determines the logic used when links for this dynamic constraint are generated. Select one of the following from the drop-down list:
- Component Order
-
Generates links between components based on the order the elements are listed on the component’s node.
- Within Max Distance
-
Generates links between any components that are within the Max Distance value (in world space) at the start frame. This results in multiple components linking to each other.
- Nearest Pairs
-
Generates links between each element and the nearest other element. This results in just one link from one element to another element.
- Max Distance
-
Specifies the maximum distance allowed between linked elements when the Connection Method is set to Within Max Distance. The default is 0.1.
Connection Update
Specifies when the connection method is evaluated for this dynamic constraint. Select one of the following from the drop-down list:
- At Start
-
Evaluates the connection method at the start of simulation (default).
- Per Frame
-
Evaluates the connection method every frame of simulation.
- Connect Within Component
-
When on, allows links between Maya Nucleus objects and components. When off, allows only links between components. This attribute is off by default.
- Connection Density
-
Specifies the concentration of links for this dynamic constraint based on the Max Distance value. This attribute is only available when the Connection Method is set to Within Max Distance.
A value of 1 maintains links, while a value of 0 results in no links. Values between 0-1 determine the probability of broken links. You can use the Connection Density Range settings to scale this attribute.
