Niagara sprite particles incorrectly face with Orthographic camera when "Velocity aligned" is set for its camera alignment.
UE-44491 seems to be the same issue but with Cascade.
Found in 4.19 CL# 4033788, 4.20 CL# 4233996, 4.21 CL# 4247867
The particles will not face the camera
The particles would face the camera while being rotated according to their velocity
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-62455 in the post.
