Importing FBX to Unity from Maya has more than one object?

[Anonymous]

I am barely new to Maya platform, while I work as programmer in Unity. I am currently working on implementing FBX from Maya to Unity for VR game. I used Substance Painter to texture the models, and I found out that the models have to be broken down to texture them. It looked good in Unity as I wrapped everything up but the Programmers have informed that they needed the models to be one whole object for VR Interaction to work. I have combined my model but yet, it comes with children under Unity's Gameobject/model. 

Is it Unity VR issue side or Maya side?
How can I combined my Model into One Object, even I combined it, it still have children in Unity's Hierarchy, regardless. How can I resolve this?

Hello @Anonymous,

thanks for your post! Maybe just the history of the combined object was left in Maya. Can you please try the following steps:

1. Select the objects in Maya that you want to combine.
2. Combine the objects at Mesh > Combine.
3. You will see that some empty groups in the scene outliner are left, containing transform nodes.
4. Select the new created mesh and all these groups.
5. Go to Edit > Delete by Type > History
6. All the empty groups should be gone.
7. Export the object to Unity.

Here is a short video of the procedure: Combine objects in Maya and delete history

Looking forward to your reply, if the steps helped to import the combined object without any hierarchy in Unity.

Best regards,

Patrick

Hello, @patrick.schock,

This was a good solution, and I was able to successfully export the FBX with no children in hierarchy, I was unable to find this solution anywhere in my research. However, Thank you so much!
