If you ever used BlenRig, you may have noticed that it pops up a text file in your text editor called "generate_customprops.py". This is a python script that the rig uses for various purposes such as automatically disabling drivers and hiding bones. When you append a BlenRig rig to another file, this text file comes with it.
I also need to execute some python script in my own custom rig, and I also have a text file. The functions in the script can be called from any Driver. All of this works fine and opens a lot of new possibilities for what a rig can do. However, if I try to append my rig to another blend file, the text file will not come with it, and has to be appended separately. Since I'm trying to create public rigs for other people to use, this is not ideal. Any help would be appreciated!
