The tyConvexHull modifier allows you to transform an object’s mesh into its convex hull, or a decompose a spline object’s polygons into convex hulls.
Mode: mesh mode converts an object’s mesh into a convex hull - spline mode decomposes a spline’s polygons into convex hull polygons.
Inflate: the amount to inflate resulting convex hulls by pushing the hull vertices along their normals.
Split elements: when enabled, a convex hull will be generated for each mesh element. When disabled, all mesh elements will be transformed into a single convex hull.
