Hi,
The problem is that I have two screens, one horizontal and one vertical, the view on the horizontal screen should be 90 degrees turned from the vertical view. An example, if the world is a simple room, on the vertical screen we see the wall and on the horizontal one, we should see the ground! But the camera has not changed is position but just turned around itself.
But I think I will certainly have to change the camera position, It could be great if not

That's why I want to change the camera view and not the object position. But perhaps there is a way to change my importer into something else?
