Composite Method group This option lets you choose the method by which Hair composites hair with the rest of the scene. Compositing options are available only with the "buffer" rendering method. ■ None Renders the hair only, with occlusion. The resulting image is ready to composite. ■ Off Renders hair shadows but not the hair. ■ Normal (The default.) Does standard rendering and composites the occluded hair with the rest of the scene in the Rendered Frame Window. Because of the occlusion, hair will not appear behind (through) transparent objects. ■ GBuffer Buffer-rendered hair appears behind most transparent objects. Transparent refractive objects aren't supported. Occlusion Objects group This setting lets you choose which objects will occlude hair in the scene; that is, if the object is closer to the camera than part of the hair array, the hairs behind it won't render. By default, all objects in the scene occlude hair behind them. ■ Auto (The default.) All renderable objects in the scene occlude hair behind them. ■ All All objects in the scene, including non-renderable objects, occlude hair behind them. ■ Custom Lets you specify the objects that will occlude hair. Choosing this option makes the buttons on the right slide of the list available. If you choose Custom but don't specify any occlusion objects, no objects will occlude the hair; that is, the hair will appear in front of all objects, whether or not it's closer to the camera than the objects. List The list of custom occlusion objects. To edit this list, choose Custom and then use the buttons on the right side of the list. Add Adds a single object to the list. Click Add and then in a viewport, click the object to add. 6592 | Chapter 21 Effects and Environments
