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.
