Common reasons why your spline gizmo is invisble

[_Aka_]

Hi

Every now and then I get complains about splines' gizmos becoming missing. Here is a compilation of the common reasons, in case it can help anyone in the future:

• Gizmos (the Unity button in the scene toolbar) being not active
  
• Show Gizmo being set to false
  
• Color having an alpha set to a too small value
  
• View Settings having the Curve option deactivated
  
• Control Point Size being set to a too small value
  

I hope this helped and have a nice day
