AEM 3D (Adobe Experience Manager 3D) lets you upload, manage, view, and render 3D content. Support for viewing and rendering is optimized for individual objects.

AEM 3D lets you view and render high-quality static, stand-alone 3D models in pre-defined environments called Stages. Basically, a stage provides "lighting" for the 3D scene and the settings for rendering in a native application such as Autodesk® Maya® or Autodesk 3ds Max®. In addition, the stage can optionally include pre-defined cameras, backgrounds, and ground plane geometry.
Uploaded 3D files that contain lights are assumed to be a stage. You can revert such assets to be simple 3D objects by opening the asset in the asset details page. Tap View Properties, then tap the Basic tab. Under the Metadata heading, from the Asset Class drop-down list, select 3D object.
When you create 3D models for use in AEM 3D, be aware of the following:
A typical 3D asset has a primary model file and none or more referenced files. Referenced files include such things as texture maps or IBL (Image-Based Lighting) images.
The primary 3D model file contains the actual 3D model geometry and definitions for the (default) materials that are applied to the model surfaces. AEM 3D supports the following primary 3D model file formats:
|Option in Autodesk Maya FBX Export dialog box||Description|
AEM 3D currently does not support external references.
|Convert NURBS surfaces to||Software Render Mesh|
Select or deselect.
If you choose to select this option, AEM 3D ignores the animation information in the file.
Select 3D stages.
Deselect 3D models.
Select 3D stages.
Deselect 3D models.
|Units - Automatic||Select. AEM 3D converts on import.|
|Axis Conversion - Up Axis||
Y-up gives consistent results when you export from Maya and is the preferred coordinate system for FBX files in this AEM 3D release.
|FBX File Format - Type||Both Binary or ASCII are supported.|
|FBX File Format - Version||FBX 2014/2015 is recommended. Other versions may also work fine.|
The following additional file formats are supported if Autodesk Maya, or Autodesk 3ds Max, or both are installed and configured on AEM authoring servers:
Material definitions in 3D model files can include references to external image files that provide texture maps. AEM 3D supports the following types of texture map files:
Materials in the primary 3D model file can reference other types of maps, but these are ignored by AEM 3D.
A 3D model file that defines a stage can reference a single IBL environment image. Currently, AEM 3D supports only 32-bit TIFF images in latitude/longitude format for diffuse IBL.
File references–other than those described above–that are present in the primary 3D model file are currently ignored. AEM 3D does not support references to secondary 3D model files.
The primary 3D model file can contain material definitions that are used with shaders such as Blinn, Lambert, or with procedural shaders. These potentially complex materials are supported only when you render using a native application such as Autodesk Maya or Autodesk 3ds Max.
For viewing purposes or when you render using the default Rapid Refine™ renderer, all materials are either simplified, substituted, or both so they can be used with a Phong-like shader. This shader supports a limited set of attributes.

See Rendering 3D assets.
A surface is defined as the surface area of a 3D model covered by the same material. This material also provides the name for the surface. As such, Adobe recommends that you name the materials included in primary 3D model files accordingly. For example, the use of specific names such as "Body", "Windows", "Tires", or "Rims" is preferred to the use of vague names such as "Red", "Glass", "Rubber", "Aluminum".
