Array modifier start/end cap error When making a curve with a "Toggle cyclic" setting and setting object with modifiers curve an array, object overlaps with himself like on the picture. You would usually solve this with Start Cap and End Cap, but I seem to get an error each time wherever I place them. The error message is:Failed to set value
This can be usually done by checking the First/Last option.
But not here, because the Curve modifier takes effect after the Array modifier.
You can use the new (2.82+) Weld modifier to merge the vertices instead.  


Array modifier to copy your objects
Curve modifier to bend the geometry
Weld modifier to merge the First/Last vertices
