Road Editing
Any change of road can take a while if it is done in a subscene, so make changes to the road in the main scene for Editor performance reasons:
Steps
Open the Hub in the scene.
Select the Entity Subscene Generator.
Click Move Back button to move road from subscene to main scene.
Make any change in the road.
In the Road Parent, press the Force connect button if you have created new segments (make sure all segments are on one line) or create paths between segments with Path creator.
Then, in the Road Parent, press the Bake path data button to bake & validate the road.
If the console shows any errors related to the road, use the TrafficObjectFinder tool to find broken road objects & fix them according to the message.
Click Generate button in the Entity Subscene Generator.
Note
By default, the config from the main scene is copied to the subscene when subscene generation is repeated.
