The oak tree that the courtyard is built around gets in the way of illustrating the background structure in Photoshop. The tree's many leaves and complex form make it difficult to mask without rendering it as a separate object. Let's turn off the tree for now and make another rendering.

8. Click the tree to select it; the leaves appear because the AEC Foliage object is set to stay in Viewport Canopy mode only when the object is unselected in order to save memory.

9. Right-click in the viewport to open the quad menus. Select Hide Selection from the display quad; the tree disappears.

10. Press Shift+Q to quickly render the scene again. The RFW appears; save the rendering as Farmhouse.tga with the same Targa options used previously.

The next step is to render the tree matted against all the other objects in the scene, as you did in Chapter 7. Use the Matte/Shadow material on everything but the tree.

11. Press M to open the Material Editor, and then press Ctrl+A to select all the objects. Click the Assign Material To Selection button in the Material Editor (see Figure 8.6). Since the Matte/Shadow material is the current material, it is assigned to the objects in the scene. In the Matte/Shadow Basic Parameters rollout, make sure that Opaque Alpha, Receive Shadows, and Affect Alpha are unchecked.
