ProjectAirSim UE plugin shows "modules are missing or built with a different engine version" after copying Plugin folder

[Yansanya]

Question

What's your question?

Hi,

I copied the unreal/Blocks/Plugin folder into my Unreal project, but when opening the project I get this message:

"The following modules are missing or built with a different engine version:
ProjectAirSim"

Include context on what you are trying to achieve

My understanding is that this happens because the plugin binaries were not built for the exact Unreal Engine version used by my project, or because copying the plugin folder alone is not enough and the plugin must be rebuilt inside a C++ Unreal project.

Could you please confirm the correct integration steps for ProjectAirSim as a UE plugin?

Context details

My current setup:

• OS: Windows11
• Unreal Engine version: 5.2.1

Include details of what you already did to find answers

What I did:

1. Built / cloned ProjectAirSim
2. Copied unreal/Blocks/Plugin into my Unreal project
3. Opened the .uproject
4. Unreal showed the "modules are missing or built with a different engine version" error
