Optimize scene size

Several functions are available in Maya to decrease the size and complexity of your scene.

Use the Optimize Scene Size window to remove empty, invalid, and unused information from your scene. For example, if you get error messages about mental ray Unknown Nodes, open the Optimize Scene Size options and choose Unknown Nodes from the list.

To open the Optimize Scene Size options:
Note: Changes made with Optimize Scene Size cannot be undone. Save your file with a different name before optimizing to avoid overwriting your original.
