It's the staple of so many tutorials this time of year. I'm following some and mostly know what I'm doing. But mostly is the operative word.

I cannot, for the life of me, figure out the Curve modifier. Sometimes it works perfectly. Other times (like now) it is an irritating failure. I have tried everything to get my array-of-lights-on-a-cord to follow the spiral curve found in the tree. I don't know what I'm doing wrong and would love some pointers.

You need to:

  • Put your object's origin at the same position as the curve's origin: Select the curve, press ShiftS > Cursor to Selected, select the object, press ShiftS > Selection to Cursor.
  • Give it enough Count in the Array modifier (or choose Fit Curve and select the curve)
  • Choose the right Deform axis in the Curve modifier (here Z as it is the object local direction that is supposed to follow the curve)
