Spline Growth rigger
A really simple script, allowing you to setup multiple to deform along path with PathDeform WCM modifier.
Has a simple GUI and even a working progress bar if you happen to use it for a lot of splines :D
1. Pick object
2. Choose how to duplicate it: Copy, Instance, Reference
3. Select splines
4. Click button
If you use Instance or Reference, you can use it to make them grow simultaneously, animating only one of objects (if you are using a cylinder for example).
Just made it for myself, thought - why not to share it with people.
