Correct glass shader i am trying to make a glass shader for a photorealistic scene that im making but i have an issue with a glass of water. My glass in real life has some edge loops in the inner part of it. I modelled them and made a glass shader.
But the inner part of it isnt refracting.





This is the best that i could make. But the top part is so bad.
I think the problem could be that you are using the light path node at the end, try this, I hope it helps.
