I am trying to render a large number of glass sheets stacked on top of each other (42 to be precise)
I bumped up the transmission bounces amount to 50 just to be sure. set up a simple 'office' environment with some area lights and 3 white walls to have some interesting refractions. I am also using HDRI as a light source.
Is there some general shader that would work well with this kind of setup (stacked glass)? Do i need to worry about different interfaces (Glass to glass, glass to air)?
See below images for the materials and sample render.
Light paths settings
Material on top side of the glass sheet (as you can see the difference is that i use 'Is transmission ray' instead of 'Is reflection ray', also i add an image with it's alpha as a factor, the image is a mostly transparent png image with some text on it)
I am aiming at maximum realism yet the glass still looks unrealistic and it is "dark" inside no matter how many transmission bounces i use, How can i improve it?
I attached slightly simplified scene so you can see roughly how i proceeded.
