Surface Association
Determines how the source and destination surface components of the skinned objects correlate to each other.
Influence Association
Determines how the components that influence the skinned objects (that is, skeleton joints, influence objects, and so on) correlate between the source and destination objects.
The Influence Association occurs in a maximum of three iterations in order to determine the best correlation. You set the Influence Association type for each iteration from a drop-down list beside each level. Set the Influence Association type based on your knowledge of the two skinned objects. As each iteration is completed, the next iteration continues using its specified Influence Association type on any remaining joints. If you are confident that only one or two iterations are required, you can set the remaining Influence Association levels to None and they will not be done.
