3D object layers from Photoshop
http://help.adobe.com/en_US/AfterEffects/9.0/WS510B8F17-8644-43ce-977F-96784840A64B.htmlFor a video tutorial about using 3D object layers from Photoshop in After Effects, go to the Adobe website: www.adobe.com/go/lrvid4113_xp.
Adobe Photoshop Extended can import and manipulate 3D models (3D objects) in several popular formats, including the following:
.3ds (3ds Max)
.dae (Digital Asset Exchange, COLLADA)
.kmz (compressed Keyhole Markup Language format, Google Earth)
.obj (common 3D object format)
.u3d (Universal 3D)
Photoshop can also create 3D objects in basic, primitive shapes.
Photoshop places each 3D object on a separate layer. Within Photoshop, you can use the 3D tools to transform (move and scale) a 3D model, change the lighting, change camera angles and positions, and change render modes—for example, from solid to wireframe mode. You can also use Photoshop to modify, paint on, and replace textures for a 3D object.
You can bring these 3D object layers in PSD files from Photoshop into After Effects for compositing and animation.
When you import a PSD file into After Effects as a composition and that PSD file contains a 3D object layer, you can choose to make the layer a live Photoshop 3D layer. If you don’t choose the Live Photoshop 3D option when you import the file, you can convert the layer to a live Photoshop 3D layer in After Effects by choosing Layer > Convert To Live Photoshop 3D. When a layer is a live Photoshop 3D layer, it contains an instance of the Live Photoshop 3D effect. The Live Photoshop 3D effect on a layer renders the 3D object according to the active camera in the After Effects composition. The Live Photoshop 3D effect works like other effects with a Comp Camera attribute. (See Effects with a Comp Camera attribute.)
When a live Photoshop 3D layer is imported, After Effects creates a camera that matches the camera used in Photoshop. The camera created in After Effects is not animated, even if the camera for the 3D object in Photoshop is animated.
A 3D object and its camera may be animated within Photoshop. To make After Effects use the animation of the 3D object or camera from the PSD file, choose Use Photoshop Transform or Use Photoshop Camera in the effect properties in the Effect Controls panel for the Live Photoshop 3D effect for the layer. In general, you can create animations and camera moves with more flexibility and convenience within After Effects.
The live Photoshop 3D layer in After Effects contains several expressions, which are used to attach it to a null layer. Use the null layer to manipulate the live Photoshop 3D layer, rather than directly manipulating the live Photoshop 3D layer’s Transform properties.
To move selected layers so that their anchor points are at the center in the current view, choose Layer > Transform > Center In View or press Ctrl+Home (Windows) or Command+Home (Mac OS). This command is especially useful for bringing a 3D object layer into the appropriate part of a scene.To reduce the amount of time that the 3D object requires to render for previews, change the layer’s image quality setting to Draft. With this setting, the Photoshop rendering engine built into After Effects creates a more simple rendered image from the 3D model. (See Layer switches and columns in the Timeline panel.)To paint on the textures of the 3D object, modify its material options, change its lighting, or otherwise edit the 3D object itself, you must return to Photoshop. The most convenient way to edit the original PSD file is by opening it in Photoshop with the Edit Original command in After Effects. (See Edit footage in its original application.)
