UE503 - Stuck at 75% after compiling while using Unreal 5.0.3

[fpibbs]

The plugin seems compiling correctly, but remains stuck at 75% while loading the demo project.

Recompile through VS19 going positive:

maybe you need to copy plugin dll (include opencv) to project "Binaries\Win64" folder, or use PublicDelayLoadDLLs.Add feature

[fpibbs]

Could you please explain better these two procedures?

[endink]

please see ue doc:

https://docs.unrealengine.com/5.0/en-US/integrating-third-party-libraries-into-unreal-engine/

specifically the “Delay Loading DLLs” section.

BTW, the author says it's a UE5 bug, I dont think so, but I'm not sure, the "75%" problem is generally caused by the inability to load the required DLLs at startup, you have two options to pass it:

1. use lazy loading
2. copied directly to the Binaries folder at the root of the project (/Binaries)
