The sweepAttack particles won't render when the player is in third person view (the view that you can see the face, press F5 2 times). In the screenshot, the particles were made by powered repeating command blocks with
/particle sweepAttack ~ ~5 ~ 5 5 5 1 10
in it.

Depends on angle. See mine https://bugs.mojang.com/browse/MC-88120

Fixed somewhere between 15w34d and 15w44b.

Reopened per MC-93298.

Affects 1.11.2, 17w14a & 17w15a

Resolving as duplicate of MC-74764, it’s the same issue.
