The geo are not overlaping but anyway I tried to change Ray Bias value but nothing changed.

The geo on the back (orange) get an normal map on it and the issues seems to be the way the light reflect on the second glass bump. They reflect differently.

Hi,

I'm encountering an issue and I'm unsure if it's a bug, an expected behavior, or something I can adjust.

I'm working on a car model where the front lights consist of multiple layers of glass. When rendering with Karma CPU, I achieve the desired result. However, when I switch to Karma XPU, the outcome differs specifically in this area. The issue arises when I add a second glass layer on top of the first. The Shader was done with materialX( transmission and transmission color)

Is this normal behavior for XPU, or is it a bug? Any advice would be appreciated.

Thanks!
