Issue:
When you are trying to find the Rendering Method Panel under the Configure Viewports menu to manually reset your Field of View to 45. However, that panel is missing .

You are using the Nitrous Direct 3D 11 driver on your viewports. According to the documentation found Direct3D drivers should still show the Rendering Options tab to pop up.


Is there any way around to get to introduce the Field of View value manually or at least rest it to 45 without resetting the whole preferences in 3ds MAX?
Solution
This setting is in the Per-View Preferences
