Hello valentina_marques8EYMQ,
I'm not a Unity user, but I work with Unreal a lot. One important step before exporting any mesh or model is making sure it's properly set up in the Maya scene.
I've uploaded some screenshots to show what I mean. When exporting models, it's crucial that the corner of each model is positioned at the center of the Maya grid—specifically at coordinates (0,0). In the images, you'll see two identical models in Maya. Both have their pivots placed at the corners, but only one has its corner aligned with the grid center.
When I import them into Unreal, the model whose corner was centered in Maya has its pivot exactly where I want it. The other one doesn't—because game engines like Unreal don’t recognize pivot adjustments made in your 3D software. Instead, they rely on the model’s position relative to the grid center (0,0).
To fix this, I recommend creating a separate layer for each model in your modular kit. This makes it easier to hide and export them individually. Then, for each model, align its corner to Maya’s grid center as shown in the screenshots. That should resolve the pivot issue you're seeing in Unreal.
Hopefully this helps you got
Good luck!
