How to Use Rigid Bind in Maya



Rigid Bind is a variation on the topic Adding Bones. With Rigid Bind the object moves less organic and more mechanical in nature.


Step One

Add a polygon plane to the workspace (Create > Polygon Primitives > Plane). In the options set the Height and Width to 6 units and Divisions to 3 in both directions.

Step Two

With the object selected, switch to the Component Mode and click the Faces icon.

Step Three

Select face one, then shift select face three, face seven and face nine and press the Delete key. Return to the Object Mode.

Step Four

Turn on the Snap to Grids feature. Select the Joint Tool (Skeleton > Joint Tool) from the Animation menu set.

Step Five

In the top view, start in the middle and click three times in one direction. Press the Up Arrow twice and click two times in the next direction. Repeat the Up Arrow and clicking until you have added eight bones to the model. Press the Enter key.

Step Six

With the skeleton selected, shift select the object and choose Skin > Bind Skin > Rigid Bind.

Step Seven

Open the Outliner (Window > Outliner). Select joint2, then select the Move Tool.

Step Eight

Notice the three axis of the Move Tool. Click the Tool Options icon. In the Move Tool options click Object Space. In this example we will be rotating the sides of the box. In other words, we will be rotating the joint around the blue (z axis).

Step Nine

In the Outliner, click joint4, joint6 and joint8 one at a time. In each case, the joint will be rotated around the blue (z) axis.

Step Ten

With the timeline at frame one, select joint2, then shift select joint4, joint6 and joint8 in the Outliner. Press the s key to set a keyframe for each of the joints.

Step Eleven

With all four joints still selected, move the timeline to frame 24 and open the Channel Editor. Change the z rotation value to 90 + Enter + Esc, then press the s key to set the keys.

Step Twelve

Reset the timeline to frame one and play the animation. If the animation plays to fast, verify that Maya > Preferences > Timeline has the playback speed set at Real Time.
