Show tertiary roads on lower zoom levels about openmaptiles HOT 3 OPEN

I had the same problem. I want to know which file I should modify to achieve a custom zoom level.

from openmaptiles.

I did a quick and dirty fix for now which seems to work in the transportation.sql file. On row 377 I added these lines to the where clause:

...
WHERE NOT is_area
  AND
     WHEN zoom_level = 10 THEN
        CASE WHEN transportation_filter_z12(hl.highway, hl.construction) THEN TRUE
        END
     WHEN zoom_level = 11 THEN
       CASE WHEN transportation_filter_z12(hl.highway, hl.construction) THEN TRUE
       END
...

It does something but I'll keep looking for better solutions.
