Problem in using .hdr file

in New Users
I only got .hr file hand .duf camera. can I use this HDRI in DAZ? I've already transmitted into tif, but I don't have a JPG for it so I don't know if I could use Uberenvironment2 to achieve it.

I'm not sure how to use .HDR files with Uberenvironment2 (though I heard it could be done). If you want to use your .HDR file with Iray, you would put the image in here: Render Settings Pane --> Environment --> Environment Map, as shown in screenshot.
Thanks mate, I succuessfully rendered it in HDRI, But how could I preview the environment before render?
