Resetting the Render Screen

Axelx10

When opening up some environments my renderscreen gets set to these Landscape demensions. I there any way to reset it back to the original default 1/1 Square.

I can get it back to default in scenes I am currently using, but not in some some environments I would like to use in Iray that I have used in 3Delight.

The environment I am talking about here is the Modern Museum by Age of Armour, but it's not the only one. Several others do this to the rendering dimensions and it drives me nuts.

I don't like settings changing that I didn't change.

You can set up the Render Settings with the dimensions you want and save that as an option.
