How to Create a Single Object that Affects Connected Instance Shapes in Maya



Imagine creating one object along with two instances of the same object. As you reshaped the first object, the others were reshaped as well. The trick with instances is that they copy the initial object at the component level. In other words, if you scale the original object while in the Object Mode, it has no effect on the instances. Once you switch to the Component Mode, the instance objects are modified.

In this example we will add a polygon cube to the workspace, then make two instances of the cube. As we reshape the original object, the instances will also be affected.


Step One

Add a polygon cube to the workspace by choosing Create > Polygon Primitives > Cube (include options).

Step Two

In the option set the Width, Height, Depth and Divisions to 1. Click Create to add your cube.

Step Three

Select the cube and choose Edit > Duplicate Special (include options).

Step Four

Select Geometry Type: Instance,set the Translate x to 3 and Number of Copies to 2. Click Duplicate Special to add your instances.

Step Five

Right-click the first cube and choose Vertex.

Step Six

Using the Move tool (w key) move the vertex and notice how the other objects are also affected.

Symmetric Objects

This is a great way to model symmetric objects such as a face. For more information, see topic, Symmetric Modeling with an Instance Object.
