Customize Asset Processing with Scene Settings

Meshes, actors, motions, and PhysX colliders created in third-party digital content creation (DCC) applications must be processed as runtime optimized product assets to be used in Open 3D Engine (O3DE). To provide the broadest support for DCC applications and scene file formats, O3DE integrates the Open Asset Import Library . O3DE uses .fbx as its primary format for 3D scene source assets. O3DE also supports .stl, and support for .gltf is enabled and currently in development.

When source assets are placed in a scan directory, Asset Processor detects the new or modified files, determines the contents of the files, and then processes the data using basic default settings. However, 3D scene files can be complex and might contain data that’s necessary for an artist, animator, or designer, but isn’t necessary for a product asset. Data in the source asset might require special handling such as processing custom normals or a coordinate space change. With Scene Settings, you can specify the data in the source asset to process and customize how it’s processed.

Scene Settings creates a .assetinfo sidecar file containing your custom processing options for a source asset. The source asset is not changed. When Asset Processor processes the source asset, it uses the options in the .assetinfo file to generate product assets.
