这种应该可以
constraints
{
       geometric
    {
        type    geometric;
        grow    false;
        selection
        {
            box1
            {
                source  box;
                min     (-0.1 -0.01 -0.1);
                max     (0.1 0.30 0.1);
            }
            ball
            {
                source  sphere;
                origin  (-0.1 -0.01 -0.1);
                radius  0.25;
            }
            blob
            {
                source      surface;
                surfaceType triSurfaceMesh;
                surfaceName blob.obj;
            }
        }
    }
}
