Currently, I’m trying to restore saved viewpoints in the viewer and I’m encountering a strange behavior when trying to restore saved viewpoints in the orthographic camera.

Basically what I do is:

• Set the viewer in ortho mode
• Save the viewpoint
• Restore the viewpoint

So you can see below an screen shot of the viewer at the moment that I’ve saved the viewpoint.

When I reload this viewpoint I get this :

The difference is the zoom. When I reload the viewpoint, I got something with less zoom.
Everything works fine for perspectives cameras.

I’m reloading the view points as below :

Can someone explains what I’m missing here ?
