I have a project I have built using character and animation from IClone.  The project runs in preview fine, but after packaging the project, when I try to open it, the application crashes and in the log, there is the message below

LogPluginManager: Error: Unable to load plugin 'RLPlugin'. Aborting.
LogCore: Engine exit requested (reason: EngineExit() was called)
LogExit: Preparing to exit.

I have moved the files for the CC3 Iclone plugin into the project folder, and within Unreal, the CC3 Iclone plugin shows as being enabled

Found the problem.  I need to have the RLPlugin disabled when I build the Unreal Engine project...

what do you mean by you disabled the RLPlugin? when I disabled it, it still wouldn't run. can you explain what you did to get the game running?
i was able to get it to run using C+ option but not with Blueprint
