Issue with EEVEE transmission, despite good config. BUG? (Solved)

Ok, So I have this eye transmission that was working on Blender 4.1, and at the arrival of 4.2 we had to update the configuration. So I followed the tutorials and videos from youtube, but it still doesn’t work. Now a similar configuration did worked on another file, so this blows my mind. What could I be missing? Is this a bug?


In the image you can see what is behind the material with the transmission shader. But we just don’t see it.
Thanks for any help. Best regards.

The material behind it was marked as Raytraced transmission, so that was the issue. No bug or problem other than that.
