Ray Tracing Translucency and Tinted Glass

Hi all. I am trying to create a raytraced windshield with the layered mesh method shown here:…9f4ce5e1e9.pdf

My main issue lies in the raytracing translucency. It seems to enable backfaces for some reason. It also disables modulate blend modes, which is what I am using for my tint material.

I also tried replacing the modulate material with a decal material. That seemed to work with the ray tracing, but not at far distances.

My main goal is to figure out how I can use raytraced translucency for my reflections, while also being able to tint my glass. If I cant, than what are some good workarounds? How have people been rendering raytraced automotive glass?

I’ve attached some write ups if that helps too. Thanks everyone!
