Realistic "dirty" glass in UE4 with Substance- is it possible?
polycounter lvl 5
We have some realistic props in production and so far our glass R&D in Substance has been an epic failure. Any thoughts, UE4 shaders, advice on achieving great realistic results like this example would be mucho appreciated!!

I've done a project for Nike a few years ago for which we had create glass in Unity before the pbr thing was a hit. We used techniques Similar to the ones in this article by Marmoset: https://www.marmoset.co/posts/tutorial-create-convincing-glass/
Main thing that we felt made the difference was the highlight. Most common shaders subtract the alpha from the specular while the specular should be rendered on top. I've not done much with transparent shaders ever since so I can't give you a working sample you could hack open. Hope this came of help.
