I have modeled two pinball flippers in Houdini. I exported them as OBJ files and imported them into Unity 2021.3. They look correct in the asset view:

They also look correct when I open them with the default Windows 3D model viewer.

However, as soon as I drag them into the scene, they flip 180 degrees about the Y axis:

My camera is oriented correctly and I have verified that I am using the correct axes in the modeling program. So what is causing this to happen and is there a way I can fix it? I know I can child them to an empty GameObject and rotate them that way but I'd like to fix the root cause, if possible.

EDIT: Here is the orientation of the right flipper in Houdini. I am saving the geometry as flipper_right.obj:

In Unity I am simply dragging it from the asset browser into the scene:

Model is oriented correctly in the Unity asset browser but flips 180 degrees when added to the scene?
