Range sfx needed :)

[dayxhep]

Hello dear community of HiveWorkShop !

I have some difficult to find a model to simulate a ring like a range of a unit.
It should be something like a 200 range units ring but a bit stronger than the selection circle, if you ever played League of Legends i'm searching Ekko's range circle :

Edit : Using selection circle with an improved size change the circle thickness and i want to keep a thin circle.

Thank you already for your answer !
