Garland length 12-100m, pitch 40cm, base E27.

The garland was created using Corona Scatter, the composition is editable
through a spline (wire). The number of lamps automatically changes depending on
wire lengths with the same pitch.
Spacing value - sets the spacing at your discretion.
By default, the lights are on (Material ID1),
ID2 - disabled.

It is important that in the spline (wire) the sharp corners must be of two vertices, otherwise the cross-section of the wire will twist and some of the lamps will look up or to the sides.
If the wire does not intersect correctly with all the cartridges, correct it through the main (yellow) vertex, the initial direction of the spline is horizontal.
Scene in mm and m.
