Rendering - Perspective
 

I am having trouble with changing the properties of perspective.

I work for a shopfitting company and need to create visualisations of the rooms from time to time, but can never modify the perspective sufficiently to create an image that suggests you are 'in the room'.

I can orientate the view and then right-click 'viewport properties' and change the settings in 'projection' but as I zoom out or move the perspective sort of resets.

Is there a way of locking projection/perspective settings or another option somewhere to modify this sort of thing?

Any help would be greatly appreciated before I throw my pc out window and install 3ds max.

Kind regards

Dave
