Source of environments used in experiments (Arena, Factory, Manu, etc.)

[Doctor-TOTORO]

Hi authors,

First of all, thank you for the excellent work and open-sourcing SpecGuard!

I’m trying to reproduce and learn from your experiments, and I’ve successfully set up the AirSim and UnrealEngine environments. However, I could not find several custom environments from AirSim Releases, such as: Arena, Factory, Tomb and so on. Are these environments based on modified AirSim scenes, or entirely custom UE4 projects?

Thanks again for your time and for making this work accessible!
