Because making good videos takes a bit of time, I have fallen a bit behind on the next rigging ones I have lined up. However, because all of the technology I explain in the videos already exists, I decided to go ahead and put it up for download! What this means is although you cannot yet see the videos where I explain how and why I made these tools the way I did, you are free to go ahead and download them and try them out.
There are a variety of different ones up there, but in particular I would like to point you to the shoulder constraint node I made in Python. This is my first Python plugin so I would really appreciate any feedback you have while using it. Please note the MEL Scripts and the example file that I have included in the ZIP as well, as these should greatly assist in using the new plugin.
