Save and setup dynamic curves for rendering

To render spline primitives animated by an AnimWire Modifier, export the dynamic output curves to an Alembic cache file. The mental ray render uses the cache to apply motion blur to the rendered dynamic primitives.

To save and setup dynamic curves for rendering

1. In the Outliner, select the dynamic output curves.
2. From the Maya main menu bar, select mCache > Alembic Cache > Export Selection.

   Maya saves the animation to an Alembic (.abc) file in thecache\alembic folder of the set Maya project.

3. In the XGen Window, click the Modifiers tab.
4. Under Modifiers, select the AnimWires modifier.
5. In the Modes section, turn off Live Mode.
6. Click beside Wires File and browse to the location of your saved Alembic file.

   XGen uses this cache file to animate the curves at render time.
