I loaded my SUMO files with all the necessary data, including net.xml, rou.xml, especially poly.xml for the buildings as obstacles and the .sumocfg. I used the omnetpp.ini from the example of veins, and adjusted some parameters such as set the number of accidents to 0, and I ran into this issue that no obstacles were detected. Also I can't see any polygons in the GUI of OMNet++ after the scenarios is loaded.
I checked the poly.xml file, which is generated by the OSMwizard. and it shoul contains all the building polygons. Also I use the default setting. And it doesn't work
How do I where the problem started and how to debug this issue. Thanks in advance
