Okay I see, in your case it's still necessary. Well we use our own small render farm, so no need for exr.
Why are you still exporting as .PSD? Are you doing more postpro after VFB+?
Yes, I made it with Optical Flares, wanted to create sort of a natural Sun Glare and it works quite well as I find. I attach it here, feel free to use it.
