UE5: Lights through the walls using Nanite, can it be solved?

Hello, I hope you are all well.

I am writing because I have a problem using nanite. It seems to me that nanite does not work with the function, “double or two side”. But is there a way to make it work on these modules or wall blocks?

I hope you have a good day.

The documentation states very clearly that nanite DOES NOT work with one sided meshes, and they have to be at least 10 cm or units thick and closed in order to avoid leakings, altough that´s not true since i´ve had all sort of leaks and artifacts even when meeting those requirements.
