I'm trying to attach some objects to a softbody via Obi Particle Attachments.
I created some particle groups in the blueprint and assigned the objects to their respective particle group in the attachments. I want the objects to maintain their orientations relative to their particle group and I don't want the attached objects to influence the softbody if possible. I've tried every option and configuration I can think of, but the behavior is always undesirable or unstable.
I want the spikes to stick out of the ball like this and maintain their relative positions and rotations as the ball rolls around.

Instead the objects drift away from the surface or roll around their local axis. They also seem to pull the softbody around a bit instead of just going along for the ride, which is undesirable.
Is there a way to achieve the behavior I'm looking for? Or maybe I'm missing something with my setup? Any thoughts are appreciated. I can link you this project if you'd like to see my setup. Thanks!
