[VFX Graph] Position Jitter in RestState with Collision SDF

Visual Effects

-

Mar 05, 2025

Steps to reproduce:

import the provided package
open the scene named SDFIssue
in the Scene View, Zoom very closely on the different VFX.

Actual results: The particle properly collides with the SDF, and due to high friction and no bounce, instantly stops on the Collider. When zooming, we can see that although they should be in rest state, some position jittering is happening.

Expected results: No jittering should occur like when colliding with other type( Plane, Sphere etc...)

Resolution Note:

Forward-ports for this version need to be handled at a later time.
