Keep the prefab connection with FBX

Question

The steps I have gone through:

1. Added an FBX in UnityProject.
2. FBX added to scene hierarchy.
3. Made Prefab by dragging the FBX into my assets.

Note that now the model became a prefab in my hierarchy. Then I added a script to the prefab and assigned some objects and methods to such script.

My problem is that when I import the new FBX in the project my scene object doesn't update as it's linked to the prefab which doesn't see the updated FBX.

Is it possible to update my prefab with the latest FBX so I don't have to rebuild the prefab and reassign all scripts every time?

Answer 1

The way I do it is outside Unity. I use the operating system's file explorer to overwrite the FBX file with the new version, then I go back to Unity, which should keep all prefabs that wrap the model intact. I find this to be the most consistent way.

Alternatively you can import the new FBX and edit your prefab to add it in there and get rid of the previous model but if this works or not depends on how you set things up in your prefab.

Answer 2

You can try this.

1. Drag the prefab into the scene hierarchy.
2. Update the prefab by adding the new FBX.
3. Apply the changes to your prefab from the inspector window.
