How to change the x-axis for pointing at the north

[GuillaumeLussier-Dulude]

Hello,
I am relatively new with City Engine, I would like inside City Engine that the x-axis point north because I use Unreal engine and where I work, They use Unreal for a simulator and the north and the south is on the x-axis. Since I only use City Engine for extract Landscape right now, I really need to be sure that north is set on the x-axis inside unreal engine.

Thanks you for your help
