Hello,

Just tried to import UnrealCV plugin for UE v 5.2 and got nasty error about package built with different version. It would be nice if you could help me please.

Can you use build.py to compile UnrealCV? If not, can you report the error when compiling?

Thanks a lot. I tried to run python build.py but I failed and I can't solve it.
Thanks again!!

@flashal1 According to your log, it seems that you use UE 4.27 to compile Unrealcv 5.2. If you want to use UnrealCV in UE 4.27, please use UnrealCV 4.27 branch. If you want to use build.py to compile UnrealCV 5.2, please specify the path of the Unreal Engine 5 when running build.py, such as build.py --UE4 D:\Program Files\Epic Games\UE_5.2

I managed to build & run it in UE5.5 by:

• copy the full repo into /Plugins/
• Open the project
• Say yes to rebuild

5 mins later it's built and the plugin was enabled in my project.

update: but it crashes in the editor when I write anything with vset in the console...

update2: ah, Play has to be activated, otherwise the whole editor crashes :D
