I recently followed along a tutorial to create a tank in blender, but whenever I try to import the asset into Unity it is in complete shambles. I'll attach screenshots on how it looks in Blender and then in Unity after the import, any ideas why this happens?
This is because the models were transformed in world space (Object mode) in Blender. To fix, you need to make everything have a common origin or space by resetting their transforms to
1. Otherwise whatever package imports these will try to fit it into their world using said transforms. To fix, simply apply the rotation and scale and maybe even the location as well with Ctrl + A.
You need to fix rotation and scale of the model before exporting It.
