  1. Resolution Note:

    Hi, due to changes having happened on the PhysX side of things. A bug which returned incorrect normals during the contact modification pipeline was fixed. This has had a negative effect on this setup that uses Convex x Convex MesheCollider pairs as a setup for contact modification.

    Without going too in depth about the repro project's details, we recommend changing the gliders to capsule colliders of similar size to the convex mesh collider used. Upon doing that most ghost collisions will be resolved due to the capsule collider change, the ones that are not will be caught by the contact modification script already present within the provided reproduction project.

    Cheers,
    AlexRvn
