How to select the whole field in viewport
in The Commons
How do you select the whole area or field in the viewport or work space to change its surface? Is this possible? Or do you always need to put a big rectangular shape and make it as a floor?

If you mean Daz Studio, then the floor is not a renderable item unless you add one in mesh (such as a plane primitive).
If you put a HDRI in the environment(render tab) and turn on draw dome and draw ground, that might give you what you are looking for.
