Boundaries node controls instances near surface or shape edges.Boundaries node has a shape node input for extra zoning via shape area.Invert shape inverts shape sides where instances are allowed to be placed.Min distance sets closest possible instances distance to surfaces or shape edges.Max distance set maximumpossible instances distance to surfaces or shape edges.Boundary scale controls instances size nearsurfaces or shape edges.Boundary rotationcontrols instances rotatation towardsurfaces or shape edges.All instances distances tosurfaces or shape edges are depends on collision radiuses of instances.
