Hello [mention removed]
Just to let you know, I’m still investigating this.
GetRelevanteParticleHandles() does look like it should return all particles if ResolutionType == EFieldResolutionType::Field_Resolution_Maximum. Still, when checking with CVD, it’s easy to spot that the CollisionGroup has only changed for the root of the cluster. Level 1 of clustering does get changed to 1 once it breaks away from the root, but the leaves are never changed from 0.
I’ll keep you informed as I dig a bit more.
All the best,
