Model assets

Currently, model files in FBX and glTF formats. For how to export these two model files from third-party tools, you can refer to the DCC Export Mesh documentation.

Model importing

After importing into the editor, from the outside, the corresponding model asset file can be obtained in the Assets Panel. It's directory structure is as follows:

• The structure of a model file without animations is as follows:

  

• The structure of the model file that contains animations is as follows:

  

The various file types are described:

• .material files are material files
• .mesh files are model files
• .texture files are model texture files
• .animation files are model animation files
• .skeleton files are model bone files
• .prefab files are prefab files that are automatically generated on import

Using Models

After importing a model file, drag the root node of the model file directly from the Assets Panel to the node you want to place in the Hierarchy Manager to complete the node creation. At this point the model is successfully created in the scene .
Alternatively, you can expand the node of the model file, select the .prefab file under the model file node, and drag it from the Assets Panel into the Hierarchy Manager to complete the creation.

Model asset Properties panel description

When the model asset file is selected in the Asset Explorer (.fbx or .gltf), the properties of the model asset can be set in the Property Inspector.

• Dumper Directory: here you can specify or view the directory location for the dumped files.
