Carla: How can I create the a geometry plane with 4 (or more)known points in points coordinate?

[quanheng123]

Hey, I have the question as title described,

For example, I 've already know the 4 (x, y, z=0)or more points in coordinate, I want to create the non-standard plane with these points, and after that I can make it become static meshes and add it in carlamapgenerator and MapRoad, make it recognised?
How can I create this non-standard Plane?

In order to do that I believe you have to model your plane with a 3D modelling tool such as Blender or even Unreal. Then, you should open the CARLA project on the Unreal editor, import the plane and rebuild the whole project.

Correct me if I am wrong, I would like to do something similar.

Thanks.@SpakMiguel ,I’ve tried in UE4， but until now I haven’t got the right solution， because creating non-standard plane in UE4 is simple, but to create it with four-known-points from coordinate, I still don’t have the right solution. Right now I thought that first I can create the plane in AutoCAD as fbx file and import in UE4 , then for next step working sush as merge to static meshes, give it direction in roadmap.cpp， set it in Carlamapgenerator and rebuild it. But can I create it only in UE4?Because it will be much complicated to add a new CAD APP in my whole Project.
Do you have an idea for that? Or what’s your thinking?

Hey @quanheng123.
Not sure if this it's what you are searching for, but in my mesh generation tests, I've found SiggiG's ProceduralMeshes to be very useful.

What @marcgpuig has posted can be helpful to you in order to create geometry in Unreal because if you do not use tools like that you can only create geometry with relative scale and in a too basic way. The other way is as you say: importing already created geometry as fbx format from an external tool and rebuild CARLA.

Thanks, that's very helpful.
