Notice when you playback the scene the straps fall off the character’s shoulders as she walks. You can fix this by constraining the straps to her body.
An nConstraint creates a dynamic link between an nCloth’s vertices and the components of other nCloth or collision objects. A Point to Surface constraint attaches nCloth components such as vertices, edges, or faces to a target surface. In this case we are attaching the vertices of the dress straps to the character’s body.
The constraint markers disappear to give you a better view of the dress straps.
Maya automatically plays back the nCloth simulation and saves it to disk.
The dress straps now stay with the character’s body throughout the animation.
