A RigidConstraint connects two Attachments or Bones and ensures they stay in the same relative position/orientation to each other. This flexibility gives it additional functionality beyond WeldConstraint, such as attaching accessories to Attachments on a character rig.
To attach two BaseParts together, versus two Attachments or Bones, see WeldConstraint.
The fastest way to create a RigidConstraint is by selecting Rigid Constraint through Studio's Create menu in the Model tab.
Note that this tool behaves differently depending on whether you click on existing BaseParts, Attachments, or Bones after the tool is activated:
- Clicking on an existing BasePart creates a new Attachment upon it as the intended RigidConstraint.Attachment0 or RigidConstraint.Attachment1.
- Clicking on an existing Attachment or Bone uses that instance as the intended RigidConstraint.Attachment0 or RigidConstraint.Attachment1.
Following the second valid click, a new RigidConstraint is created to connect the two new attachments. If either the first or second click is not made on a BasePart, Attachment, or Bone, the workflow is canceled and no constraint is created.
