reflection with a small specular highlight. 0% specifies a reflection with a large specular highlight.
The contribution of the layer color to the color of the specular highlight. 100% specifies that the highlight color is the color of the layer. For
example, with a Metal value of 100%, an image of a gold ring reflects golden light. 0% specifies that the color of the specular highlight is the color
of the light source. For example, a layer with a Metal value of 0% under a white light has a white highlight.
Specify resolution to use for rendering shadows
The Advanced 3D rendering plug-in is used to render compositions containing intersecting 3D layers. To render shadows, the plug-in uses shadow
maps, which are images rendered from the point of view of each light source. Normally, shadow resolution is computed automatically based on the
composition resolution and the quality settings of the layers. If normal resolution doesn’t create the quality you want, odr renders too slowly, you
can adjust the shadow map resolution. For example, if shadows are blurry and the Shadow Diffusion material option is set to 0, increase the
shadow map resolution. Or, if shadows render too slowly, decrease the shadow map resolution.
When a shadow-casting layer intersects another layer, sometimes a small gap occurs behind the intersection that is supposed to be shadowed. To
decrease the size of the gap, increase the shadow map resolution.
1. In After Effects CS5.5, and earler, choose Composition > Composition Settings, click the Advanced tab, and click Options.
2. Choose a value (in pixels) from the Shadow Map Resolution menu.
Choose Comp Size or a resolution larger than the composition size for best results. Lower resolutions may result in shadows that appear
blurry.
Stereoscopic 3D
Stereoscopic 3D video can be created with Adobe After Effects CS5, and there are new workflows and tools available for it in After Effects CS5.5
and later.

Stereoscopic 3D camera rig (CS5.5)
After Effects has a Create Stereo 3D Rig menu command, allowing you to turn a 3D composition into a stereoscopic 3D composition. The Stereo
3D Rig creates all the elements for you, including the 3D Glasses effect.
Make a stereoscopic 3D camera rig by first creating a composition with 3D elements in it. A composition that contains items such as a 3D
collapsed precomposition or 3D elements in the composition itself works well. If you already have a camera in use, you can select it when creating
the stereoscopic 3D camera rig. If no camera is selected, then a new camera (named Master Cam) is created. Choose Layer > Camera > Create
Stereo 3D Rig. The rig only works with two-node cameras.
The rig is produced by creating a master camera or by using the existing selected camera in the composition. There are left eye [compare Left
Eye] and right eye [compare Right Eye] compositions. Each composition has a camera linked to the master camera, the original composition
nested in them, and an output stereo 3D composition [compare Stereo 3D]. The output stereo 3D composition nests both eye compositions and
contains a layer called Stereo 3D Controls. This layer contains a Stereo 3D Controls effect for controlling the rig and a 3D Glasses effect that
combines the left and right eye compositions into a stereo image. (see 3D Glasses effect.)
The Stereo 3D Controls effect is an effect built as part of the Stereo 3D Rig and does not reside in the Effects and Presets panel.
The Stereo 3D Controls effect has the following settings for Camera Separation and Convergence:
Center places the left and right camera on either side of the master camera. Hero Left places the left camera in the same spot as
