On the first wall in the section set Unk4=262144.
This adds a polygon to the top of every wall in that section, set at the height of wall_0.
To turn off the ceiling polygon for a particular wall, use Unk4=524288
As Bill says, the groove will be transfered to the ceiling too, so set the groove darkness (in the .grv file) to zero for all the references within the tunnel.
use .tex setting 6 to map textures to the roof of your tunnel
e.g. for the bit directly over the asphalt:
1 0 0 10.0 10.0 asphalt
1 0 6 10.0 10.0 roof
Never thought of doing it that way Pirenzo
the way I did mine was as follows
use 2056 walls in your gtk for the tunnel area
set the height
in your tex file you will need to have an entry as follows
2056 2 6 1.5 1.5 brdgin ceiling tunnel
2056 3 1 2.0 8.0 brdgl left wall tunnel
2056 2 1 4.0 4.0 brdgr right wall tunnel
notice the first entry the 3rd number is 6.
This number makes the ceiling visiable and is set to the height of your 2056 walls.
gplea's site has a tutorial that explains the texture file and the link is here
If you want a groove in the tunnel area then it must be built in the
ashpalt texture itself and not through the groove file.
Hope this points you in the right direction
Now you have 2 options.
I will have to try your way Pirenzo
