Hello im creating this material for my glasses by using aistandard surface but when i set the the transmission to high which suppose to resulting looking like glass, it becomes black like this

the glass and the frame of the the glasses are two separate mesh btw. How do i fix this??

I even tried using a different aistandard but it still end the same way

It works fine for me. Have you adjusted the ray_depth settings? Btw, why aren't you using toon for the glasses?
