Why the Position be change to (0.0.0) when the Import Gameobject ?
A Map Object included some build and tree design by Artist,and export the scene,When i import it,All the GameObjects of the Map would be Changed to (0,0,0),But when i creat i new project and import it,would be ok!

Did you forget to save the scene before exporting it?

Check the import settings on the gameobject, and turn off import animations if you don’t have them. This is an annoying issue, and had me pulling my hair out.
