Paste Weights (Replace): active influence values are replaced with weights previously stored in memory via Cut/Copy Influence Weights, discarding previous weights on the influence.Paste Weights (Add): using weights previously stored in memory via Cut/Copy Influence Weights operation, merge them into the current influence.Cut Influence Weights: same as "Copy", but sets influences to 0.0 after.Copy Influence Weights: for currently selected influence, copies values across all vertices into memory to be later used for Paste Weights operation.To make finding influences easier, use Influence Filter to list only those you currently need. The list also contains a special item to select layer mask, and, if skinCluster "Skinning Method" is set to "Weight Blended", there's also an item to edit dual quaternion blend weights: Some operations support multiple selected influences, in that case, use ctrl-select (or shift-select) to select multiple items. Selected item in the list is an active influence, being a target for operations like paint, copy/paste, etc.

This list shows skin influences (joints) of currently selected mesh. Layer opacity is one of the ways to control transparency in a layer value 1.0 means that layer is 100% enabled, while 0.0 effectively turns layer off (0%) adjust properties of the selected layer. Weights that were painted in disabled layers do not get added to the skin cluster.


Tools tabs: various tools for skin weights editing.Influences filter: options for filtering influences list.Influences list: select target influence to paint weights for, or a group of influences for some other operation.Layers list: this is where you select active layer, and can also add/remove/arrange them.

This is how the main window of ngSkinTools is laid out:
