When using animation layers on controls with proxy attrs the connection between the proxy attr and the host node will be broken.
Steps to recreate:
- Select a control with proxy attrs on it
- Create animation layer from selection
- Add key(s) on the new animation layer
- Merge layer to base animation
- Delete old layer
- The proxy attrs are now broken.
I’m pretty sure this is a Maya bug of sorts, but I wanted to know if there is a good work around.
