NVIDIA RTX Caustics 4.27 Materials behave abnormally after enhanced translucency is enabled

I am using NVRTX_caustics-4.27. When enhanced translucency is enabled, the light shines on the material through the translucent glass, and the material behaves abnormally. May I ask what is the reason?

The left side is the normal material realization, the right side is after the glass irradiation

Hello @zhanghan0929 and welcome to the NVIDIA developer forums!

Would you be able to share the material properties of the both the glass material and the material behind it that you are using in this setup? I think this might help any Caustics experts to better understand what might go wrong here.

Thank you for your reply. This is my test project, which has a glass ball material and a leather material. Up close, the normal texture seem to be behaving abnormally. I hope to get your answers.
