MRG - Potential issue with graphs being duplicated in game builds

Audi has [Link Removed] saying they cannot duplicate graphs in a game build. They are off launcher, not a custom build.

Slack thread [Link Removed]

“We are using MoviePipline with a MovieRenderGraph which works fine in Edtior builds but in Gamebuilds we get tons of ensures and the Variables in the graph are not set. We using the launcher version and actually not doing anything special here just queuing a job with a movie render graph.”

(When they made a repro project they noticed the callstack posted in the ticket might not be the root cause)

”So actually i could not reproduce the Copy error in a blank project but actually the code does more or less the same, I will look further into it.

But this also showed that my original issue was not coming from that Ensure in the first place.

If you look into the Reproducer Project you can see that in Editor builds the variables of a Movie Render Graph Config can be set correctly via C++ but this does not work in Game Builds. I am also not able to step into UMovieJobVariableAssignmentContainer::SetValueString() to see whats going on there.”

Repro project is attached to this ticket. Please see more information below and in the EPS.
