FYI - exr file export from Photoshop

Newbies have been trying to figure out all the basic methods - one that comes up is how to save files in exr format.

Photoshop can save in the exr file type for skyboxes - but in order for Openexr to appear as a choice in Save As, Image > Mode needs to be set to 36 bits/channel.  I saved without alpha for skybox - don't know if there is a way to use alpha in skybox.

A dialog opens asking for Compression choice - I picked None and it uploaded, but there may be a better choice.
