Is it possible to automatically import custom maps without UI interaction?

[wthwlh]

Version: Carla 0.9.6, UE4 4.22.3 on Ubuntu 16.04

Target: build shipped package (with ue4-docker) with customized map included which I could load as map in PythonAPI

Background: theoractically, all UI interactions could be transformed into the file changes. So when my developers add a map (.fbx and .xodr and all .png used), I want to apply their changes in the make package process and ship a product with custom map supported.

What I have tried:

1. Import New Maps from UI, and build package from Editor, it works like a charm.

2. Import New Maps as standalone assets, and build it with carla-docker, the map could be called with PythonAPI, but their is no map/route on the screen. I guess it's because I cannot add physical property in this case as it mentions

The imported map won't have collisions, so they should be generated manually

3. Right after I imported my map (say my map called foo) in UE4Editor, I searched over all "foo*" files and copy n paste it to correspond locations in carla-docker, also I add my own map here in ini file as "MapsToCook" to declare that I want to build my own map. However, when I build my package by make package, it shows that UE4 cannot find my map.

Are there any suggestions? I guess I still need to add some path/materials somewhere to tell Carla I want to import my map into games. Am I thinking on the right track? What files would be generated when a new map is imported? Is there a hidden tool inside carla/ue4 to generate CollisionBox when import .fbx?

Thanks.
