Growth animation with velocity data

[ldotchopz]

Probably not the most elegant solution.
But if you extrude your spline (by zero), and then use object bind at vertices mode, it should work.
At least, it works when I quick test it now.

Check the attachment.

Btw... how did you animate this unfolding of the spline?
Looks cool.

Cheers!

Hey, 

I tested your setup with my spline and it doesn’t work unfortunately, i think it has something to do with the way my spline deforms with modifiers.

I have added your file back with the animated spline if you fancied another crack. Also, should answer your question on how it was animated. The key is to put a slight bend in it and then add another bend to curl it.
