# Revision history [back]

If it helps, I would like to add some diagnosis. When there exist more than one roads loaded through the world file, camera does not show the roads except the first one. Meaningly, if you have a word file like below:

<road name="road_1">
....

EDIT: After wandering around the forum, I found this. Most probably, there is an unconsidered trigger that changes some visibility flag to GZ_VISIBILITY_GUI, which causes a visual to be drawn in GUI but not in a camera sensor as clearly stated by @nkoenig.
