Though you can import composited files with 3D information into After Effects, you cannot modify or create 3D models directly with After Effects. After Effects treats each composited 3D file from another application as a single 2D layer. That layer, as a whole, can be given 3D attributes and treated like any After Effects 3D layer, but the objects contained within that 3D file cannot be manipulated individually in 3D space. To access the 3D depth information and other auxiliary channel information in 3D image files, use the 3D Channel effects. (See 3D Channel effects.) 3D Channel effect plug-ins from fnord software are included with After Effects to provide access to multiple layers and channels of OpenEXR files. (See Using channels in OpenEXR files.) After Effects can also import baked camera data, including focal length, film size, and transformation data, from Maya project files as a single composition or two compositions. (See Baking and importing Maya data.) After Effects imports camera data saved with RLA or RPF sequence files. (See Import RLA or RPF data into a camera layer.) Softimage PIC files have a corresponding ZPIC file that contains the z-depth channel information. Although you can't import a ZPIC file, you can access the additional channel information as long as the ZPIC file is stored in the same folder as the imported PIC file. Similarly, Electric Image (EI) files can have associated EIZ files with z-depth channel data. As with ZPIC files, you cannot import EIZ files into After Effects; instead, you simply store them in the same folder as the EI files. For information about creating EIZ files, see your Electric Image documentation. Note: Some 3D applications, such as Cinema 4D, can export an After Effects composition directly. A common technique when working in a 3D modeling application is to insert null objects, such as null lights or null locator nodes in the locations where you want to composite in an image in After Effects. Then, after you have imported the 3D file into After Effects, you can use these null objects as a reference for the placements of other visual elements. Online resources about importing and using 3D files from other applications Lutz Albrecht provides a two-part document on the Adobe website about integrating 3D applications with After Effects. These articles cover the creation of UV maps, mattes, and channels from various 3D applications, including Maxon Cinema 4D, NewTek Lightwave, and Luxology modo. The articles then show you how to use RE:Vision Effects RE:Map and fnord ProEXR plug-ins to use that data in After Effects. Chris and Trish Meyer explain how to use data from 3D applications in After Effects in an excerpt from their book Creating Motion Graphics on their website. Tyson Ibele provides tutorials on his website that show how to use output from 3ds Max (3D Studio MAX) in After Effects. Dave Scotland provides a pair of tutorials on the CG Swot website in which he demonstrates how to create RPF files in a 3D application and how to use RPF files in After Effects. The first part explains the RPF format and how to create RPF files in 3DS Max. The second part shows how to use the Object ID and Z depth information in an RPF file within After Effects, using the ID Matte, Depth of Field, Depth Matte, and Fog 3D effects. Eran Stern provides a video tutorial on the Artbeats website that demonstrates the use of 3D tracking software that solves for camera movement so that additional elements can be composited into the scene and appear to honor the same camera movement. This video tutorial uses Pixel Farm PFHoe, but the techniques can be applied to almost any matchmoving software. Bartek Skorupa provides a script on his website for exporting camera and object data from Blender for use in After Effects. He also provides a sample project and a video tutorial that show how to use this script. Harrison Ambs provides a two-part video tutorial on the CGTUTS+ website that demonstrates how to import data from Cinema 4D into After Effects: part 1 part 2 Paul Tuersley provides a script on the AE Enhancers website for transferring a composition from After Effects to Cinema 4D. Import RLA or RPF data into a camera layer To the top After Effects imports camera data saved with RLA or RPF sequence files. That data is incorporated into camera layers-one for each camera in the sequence-that After Effects creates in the Timeline panel. You can access the camera data of an imported RLA or RPF sequence and create a camera layer containing that data. 1. Add the sequence to a composition, and select its layer in the Timeline panel. 2. Choose Animation > Keyframe Assistant > RPF Camera Import. Note: To create an RLA or RPF file with the camera data in 3D Studio Max, save your rendering in RPF format with Coverage, Z Depth, and Alpha Channels enabled. Dave Scotland provides a pair of tutorials on the CG Swot website in which he demonstrates how to create RPF files in a 3D application and how to use RPF files in After Effects. The first part explains the RPF format and how to create RPF files in 3DS Max. The second part shows how to use the Object ID and Z depth information in an RPF file within After Effects, using the ID Matte, Depth of Field, Depth Matte, and Fog 3D effects.
