Airflow/mesh tiles let sunlight pass

If i recall correctly, they made it that way on purpose because of space and problems or something. If thats the case, its not a bug.

Possibly. I do not remember that and some confirmation would be nice. Interestingly, some usually quite well informed people were surprised by this observation.

But if the devs say "not a bug", that will be fine and I will just start to use this. Would save me making a lot of glass.

Better for me if they make the artificial light going through airflow and mesh, instead of blocking sunlight, because my whole system (panels & gas grass) is relying on this (I was aware of this difference from a long time and always used it on my advantage)...
