How to edit the road surfaces in the map with UE4 or other methods

[SOTArt]

Currently, I am using CARLA to collect radar simulation data for urban roads. However, the roads are very smooth, and I wish to edit the road surfaces using UE4 to create a more realistic, uneven terrain. This requires the source files, as without them, I am unable to make any modifications. So is it possible to provide source files for UE4 development? Or if there any other methods to edit the road surfaces?

You can get the source code for Carla following this guide "https://carla.readthedocs.io/en/latest/build_linux/". It will also show you how to install Carla's version of UE4 4.26. Note that when you apply to get the version of Unreal engine from the EpicGames repo you will need to of first linked your Github account with your EpicGames account (Make sure you do this using the same email for both).

unfortunately i have never had the windows version working however i know people have been able to. However to save yourself a lot of time i look into maybe trying to dual boot a linux system along side and working with that! Not saying it is not possible by any means but in terms of saving time and complexity

Thanks for your reply. I would consider using Linux. By the way, have you tried to edit a map successfully on Linux before?

Sorry for the late reply i have edited the map in the sense of adding feature like Road side tags but never the actual architecture of the street or surrounding buildings!

How do you open the file and edit it, I can't open it right now

[o-antill]

do you have the unreal editor installed ? The carla specific version ?

[SOTArt]

so for example for my case i added a plane and then added an image to it

I konw what you mean,but now I can’t open the file. I ask another question at here: #8025 (comment)

so for example for my case i added a plane and then added an image to it

And when you added the picture upon the road,if you use the camera or lidar to scan it,could you get the information just like the distance,width and height of the picture or the point cloud?

i didnt test it with a lidar but with a camera and using OpenCV i got it working
