| # Copy this file into your maya scripts directory, for example: | ||
| # C:/Documents and Settings/user/My Documents/maya/scripts/ml_copySkin.py | ||
| # | ||
| # Run the tool by importing the module, and then calling the primary function. | ||
| # From python, this looks like: | ||
| # import ml_copySkin | ||
| # ml_copySkin.ui() | ||
| # From MEL, this looks like: | ||
| # python("import ml_copySkin;ml_copySkin.ui()"); | ||

| # | ||
| # Copy a skinCluster from one mesh to another, or to a selection of vertices. | ||
| # If no skin exists on the destination, one will be created with the same influences. | ||
| # Otherwise any missing influences will be added in order to copy accurate weights. | ||

| # | ||
| # Input a source mesh into the "Source Mesh" field by selecting a mesh and pressing the | ||
| # "Set Selected" button. | ||
| # Select destination meshes or vertices, and press the "Copy Skin" button. | ||
