Auto-rotation FBX model
I have a problem with model rotation.
Some models opened as rotated to 180 degrees.
But the same model opened correctly in "3D Model Viewer

You can download the model here

How to detect a correct rotation of the model and rotate if this required?

Thank you
I have also seen that the orientation of some models is not correct. I have no clue on how the correct orientation can be determined.

Maybe there is a problem in assimp library. The open3mod application that you mentioned uses a very old version of assimp library and there the model is correctly oriented.


But a newer assimp viewer that comes with assimp library also have some problems with  orientation - see the following screenshot where the person from the model should be visible from the side or from the front, but it is visible from upside down:
