Rendering wrong camera due to locked "View to Render"

If your scene contains multiple cameras and your test render job is still rendering the wrong camera:

"View to Render:" may be locked.

In 3ds Max, open the "Render Setup" window. (F10 or click on the Render Setup icon)

[View to Render: (pull-down with selected view or camera)] [Lock Button]

Check the [Lock Button] and make sure its not activated.
