Refraction Override through multiple layers

[thr]

Hi all - I'm realizing when I use refraction override the backplate does not look correct through two pieces of glass. It looks like it's as bright as it would be through one - see attached image with indicated area... is this a max depth issue?

I don't think it's a max ray depth issue, but you can increase its value to be sure. It's more likely that your glass has too low absorption. Try increase it and see if that helps.
