@medeamajic, ok , now i see that there is a seperate ZOOM value box for isometric cams- that works /afffects render and viewport.
Medeamajic, when you say "I think if you use the isometric camera with the orthoganal views it will work." , do you mean selecting "top left bottom right etc" ?
As far as i can see , top left bottom etc views are all seperate cameras , ,ie when in them i can see the scenes cameras , its not changing the scene camera to a top /left etc view.
and you said "An isometrci image should not rotate at all."
..the isometric camera does allow rotation ....im confused......sure the other top left side etc dont like u said.
"Did you change the director's camera and camera 1 to isometric? The render does look like one of the images."
I just added an isometric cam . I notice now that the production frame can be enlarged by dragging ,

dunno mate , bit tired, cant think "straight".
