Working with the FBX Exporter Setup and Roundtrip
25 Mins
Unity and Autodesk collaborated to create a plugin that allows for easy transfer of 3D models between Digital Content Creation (DCC) apps (currently Maya and 3DS Max with others on the way) and Unity. This allows artists to test their models in the engine, make changes as necessary in their DCC of choice, and have those changes update in Unity in real time. What previously required multiple cycles of exporting from a DCC app and importing into Unity has now been reduced to two clicks of the mouse. In this tutorial, you will learn how to adjust and work with Autodesk files back and forth with Unity.

Working with the FBX Exporter Setup and Roundtrip
Exporter Setup
Download and import the FBX Exporter from the Unity Asset Store.
From the Edit dropdown go to Project Settings > Fbx Export. The export settings will appear in the Inspector.
In the Integration section of the Inspector, select the 3D application you have installed on your machine and click Install Unity Integration (Figure 01).

Save Plugin Location
When prompted to Select Location to save integration, navigate to the FbxExporters folder that was generated in your project and click Select Folder.
The plugin will install and open the selected DCC application. The FBX Exporter options will be located in the File dropdown under a custom Unity flyout (Figure 02).

The FBX Exporter Roundtrip
Select the object in the scene that you wish to send back to the DCC.
In the Hierarchy, right-click over the object and select Convert to Linked Prefab Instance (Figure 03).

Open FBX and Modify
In the DCC app, navigate to File > Unity > Import. The DCC will automatically open to the appropriate project path. Select the generated FBX.
Make any desired changes to the model (Figure 04).

Export and Return to Unity
Navigate to File > Unity > Export.
Return to Unity, and the changes will automatically update to the Mesh (Figure 05).
