3DS Max Export | Animations to Unity & UE4 Errors . How do I fix it?

Hawkena

I am having issues importing a rigged and animated model into Unity and Unreal Engine 4. In UE4 I get a multiple root error and cannot import while in Unity the model imports but the animation breaks and portions of the skin do not move with the rest of the animation.

Please help. I attached links to the model's hierarchy and error I have been receiving in UE4.

Any help is greatly appreciated. Thank you for taking the time to read and help me.

EDIT:: The image below can be hard to read. Open it in a new tab to be able to view my hierarchy. Thanks

On a phone atm but, ue4 only accepts a single root hierarchy. So make sure all hierarchies are linked to a common hub bone.

Hawkena

That's what most of my research told me as well but if I play with the links I will probably have to redo all of the animation I have already done for it. That is my predicament.

musashidan

You won't as long as there are no loop depencies.

link all hierarchy roots to a master.

Hawkena

I see. Is it possible with what I have now? (From the image above)

EDIT:: I tried linking everything in the schematic view to the Master Controller and it messed up the animation pretty bad. The skin stayed intact but the animation died.

Is it a custom rig or did you use CAT? 

Hawkena

I created a custom rig for it because I needed extra controls to make sure the wing membrane deforms properly. However I do have a CAT Rig for the character as well.

Make sure when exporting that you're only exporting bones and the geo as the skeletal mesh. No dummies/helpers/controllers/constraints.

Hawkena

I did that actually and still get errors. I also tried without baking the animation and got unsupported controller types.

EDIT::: Aaaaaaand I have no idea what I did but everything fixed itself after a computer restart. *Table Flip*

Musashidan. Thank you so much for being patient with me and helping me with my problem.

The following helped me` I selected model, bones and create a copy, then I exported a copy of model and this issue was fixed.
