Hi Kevin,

First of all, with your curve setup Network will achieve the same result and no bunching at the end.

If using Sweep the scaling rail should cover the full extent of the sweep, in your case the scaling rail is just short of the end of the rails that's why you're getting a bunching effect at that end because sweep gets to the end of the rails then has to come back on it self to honour the scaling rail length.

If you extend the scaling rail past the end of the sweep rails then sweep and you will be happy :)



Cheers
