app = MyApp()
app.run()

Here’s my code. As you can see I’ve even tried grabbing the camera position as I zoom out with the right mouse button (that works to bring it into view). However, setting the camera position to that value or even playing with the Hpr does nothing seemingly! I just want the camera to see my rectangle from the get go.

self.disableMouse() solved it.
