Standard Helper Objects

Helper objects play a supporting role, like stage hands or construction assistants.

The helpers in this section serve mainly as precision and drawing aids. You can find links to other kinds of helpers in the "Related" links, below.

Topics in this section
  • Dummy Helper
    A Dummy helper object is a wireframe cube with a pivot point at its geometric center. It has a name but no parameters, you can't modify it, and it doesn't render. Its only real feature is its pivot, used as a center for transforms. The wireframe acts as a reference for transform effects.
  • Container Helper
    The container is a helper object that can control a collection of other objects.
  • Crowd Helper
    The Crowd helper object acts as the command center for controlling crowd simulations in character studio.
  • Delegate Helper
    The Delegate is a special helper object used in crowd animation.
  • Expose Transform Helper
    The Expose Transform helper exposes values of non-keyed objects for use in expressions and scripts. This lets riggers and animators access a select set of transforms for an object, and between an object and its parent, such as a bone in an IK chain. For example, using the Expose Transform helper, you could write a script or use parameter wiring that tests the angle of an character's arm bone that's controlled by IK (thus, has no keys), and once it exceeds a specific value, rotate the corresponding clavicle bone to deform the shoulder area.
  • Grid Helper
    The grid, also called User Grid or Custom Grid, is a 2D parametric object with adjustments for overall size and grid spacing. You can move and orient user grids anywhere in world space.
  • Point Helper
    Point provides a specific location in 3D space that can be used as a reference or by other program functions.
  • Tape Helper
    Tape provides an on-screen "tape measure" for determining and setting distances. The tape is composed of two named objects, in the same way targeted lights and cameras are. By default, these are named Tape### and Tape###.Target (the ### is a three-place number). The tape and target icons are connected by a line representing the current distance between them.
  • Protractor Helper
    Protractor measures the angle between a point and any two objects in your scene.
  • Influence Helper
    Use the Influence Helper to soft select vertices and apply proximity-based falloffs to effects.
  • Arrow Helper
    In Fluid simulations, Arrow helpers are linked to emitters, colliders, guides, and foam masks to provide a physical direction to follow.
  • Volume Helper
    Use Volume helpers to define the boundary of objects in a Fluid simulation.
  • Compass Helper
    Compass displays as a non-rendering compass rose, with indicators for North, South, East, and West. A compass is part of a Daylight or Sunlight system; you create a compass automatically when you create sunlight. In a Sunlight system, the orientation of the compass indicates the orientation of the scene, relative to the path of the sun (the ecliptic).
