Datasmith export vs FBX export shows different orientation

Development Pipeline & Plugins

Hi everybody,

Has anybody noticed that the model exported to FBX using 3dsmax has a different orientation compared to the Datasmith export? or is it just me?

Also, when I exported a simple plane model to a Datasmith file and imported it into Unreal Engine, I placed my Player Start actor on top. However, when I pressed play, my first-person player fell through the plane model. But when I exported the same model to FBX, my first-person player stayed on top of the plane.

Using Datasmith exporter 5.5.3
Looking forward to your help.

Thanks,
Leo
