Description

CreateNonOverlappingConvexHulls (v1)

Generates convex hull representation for the bones for simulation

Input(s) : CanExceedFraction - Fraction (of geometry volume) by which a cluster's convex hull volume can exceed the actual geometry volume before instead using the hulls of the children. 0 means the convex volume cannot exceed the geometry volume; 1 means the convex volume is allowed to be 100% larger (2x) the geometry volume. SimplificationDistanceThreshold - Computed convex hulls are simplified to keep points spaced at least this far apart (except where needed to keep the hull from collapsing to zero volume) OverlapRemovalShrinkPercent - Overlap removal will be computed as if convex hulls were this percentage smaller (in range 0-100) CanRemoveFraction - Fraction of the convex hulls for a cluster that we can remove before using the hulls of the children
