Substance Painter to Corona?

[Sintel]

I saw this on Allegorithmic forum and find it's better than default V-Ray output configuration in Substance Painter. It looks more similar to what I see in Substance Painter viewport. I tried doing a same method with Corona and of course, it doesn't looks the same, which in glossiness. Tried with glossiness² as default Corona output configuration in Substance Painter but it doesn't matter, too. There's small difference in glossiness. Could somebody help me for a good workflow. Is GGX problem? I do not really want to use V-Ray anymore.

Currently Corona applies curve to glossiness map, so exact match can bit a little tricky. Nevertheless there been attempt to overcome this, you may want to look at this: https://forum.corona-renderer.com/index.php/topic,9489.0.html

Hopefully that curve will be removed someday.
