Cas mass copy weight 4.0.0 for Maya (maya script)

This wondrous tool will automatically copy skin weight from source objects to your target objects.

It will even bind your target objects to the right joints for you.

So , for most of the time you just select top parent of the model that you want your skin to copy from and then add the selection of target objects and just copy weights over.

It will bind your target objects to the joints associated with source objects and copy the weights over.  If there are no exact vertex match, then it will interpolate as best as it can.

This tool is bit different than some you may find commonly in the internet. Differences are:

It is simple to use. Click source , Click target , Perform copy. That is it. It is that simple.

Your target object can be name independent , topology independent , number independent. It interpolates skin weight value as best as it can.

Target objects do not have to be bind to any joints. It automatically binds to the source joints.

Very useful when you create LOD model. Select top group node of high polygon model , add selection of top group node of low polygon model. Then perform copy weight.

Very useful when you have existing skinned model and want to add something to it. Add T-shirts to your existing skinned character model and copy weights over. You are already 90% done.

Automatically convert rigid skins to smooth skin.

Automatically prunes resulting skin weights to your specified value

You do not save your skin weights to disk and then load them into another set of skinned objects. It transfers directly within Maya so you need to have both source and target models in one Maya scene. Once you have copied the weights over you can safely delete the source models if you chose to.

If you are a character artist and need to do LOD models and bind them, this tool will save your time SO MUCH. Once you have used it and know what it can do, you just can't do it without.

How does it work?

Well, to my surprise, Maya does have a decent weight copier. But it is not very intuitive to use. Like most of the Maya default tools, this script automates lots of process and utilize Maya's built-in skin copying function in a way that I felt it should be.

Only one selection for source object is allowed. But you can have as many target objects selection. If you have many source objects then group them together and select the group node for the source object selection. Only works with polygonal objects.
