I thought Maya and Unity both used y as the up axis? Can you show a picture of the model? Try this thread: https://docs.unity3d.com/Manual/HOWTO-FixZAxisIsUp.html And this one (3DS Max, but should apply to Maya): https://forum.unity3d.com/threads/how...x-unity.10343/ I haven't run into this issue, but can you not just rotate the model in Maya, freeze transformations, then export?
