Hello
@drmaboul
In order to have this automatically, you need to respect the folder structure - and in particular the folder that contains textures.
For example, let's say your track is named "test_track"; typical folder structure should be:
\...\assetto corsa\content\tracks\
test_track\, and inside:
\ai\
\data\
\ui\
\test_track.kn5
\texture
IMPORTANT, as this will be used by the exporter when setting up materials/shaders. Use it to store all the textures you plan using for your track.
This should not exist in the final track folder (the one you'll use in game), because it will be included into the kn5 file, after the final export.
See the guide intro,
here.
Good luck and let us know what you are working on
