 Culls particles inside Implicit_, and coincident particles (defined by being within 1/20'th of the size of the domain from one another), truncates at CollisionParticlesMaxInput_, and returns a bounding volume hierarchy of the remainder.
Public function Static FSimplicial *

 Culls particles by importance (See `FTriangleMesh::GetVertexImportanceOrdering()_), and returns a bounding volume hierarchy of the remainder.
Public function Static void

UpdateImplicitFlags ( FImplicit* Implicit,
const ECollisionTypeEnum CollisionType
)

 Calls SetDoCollide(false)_ and SetConvex(false) on Implicit_ if CollisionType is `ECollisionTypeEnum::Chaos_Surface_Volumetric_.
