Hello...^_^

:slight_smile: i want ask about how to installed software of openexr (www.openexr.com) for blender3D ?

Blender can render into OpenEXR format (it doesnโ€™t matter which software you will later use to view the files), and the link you provided is the official website where you can download plugins and software to view the files in this format.
