Regression: Tested in UE5/Release-5.0, this issue also occurs meaning regression is no.
The Niagara System appears to jitter whenever a force is applied after the Rotate Around Point module. If the Rotate Around Point module is placed after any forces, the System creates a ring that does not move in any direction.
Actual Result: The Niagara System creates a helix moving positively in the X axis while also jittering
Expected Result: The particles respect the existing forces applied to it, and don't jitter as they rotate around the point and move positively in the X axis
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-171604 in the post.
