I would just like to get some feedback to see if people are interested:
Hmm looked your youtube.
Normally i’d use a path follow for that, it will give me the same result, or i do it in graph editor making use of curves there.
when using path follow i currently see not much difference, though I dont see what your addon will improve on it.
Perhaps you automated some things in here, set root of path at object origin or so ?, is that what the tool does ?.
I am very interested. I do not see any code online to download. I would be happy to help you with the code if you have hit a road block. Please let me know. I would at least like to test it.
