On UE 5.4 Source build.
Ran into an issue where it seems that the in-game OpenColor IO display extension gets garbage collected after 30 seconds, followed official documentation to implement the plugin. Apply color conversion to the Level Viewport and Play in Editor with OpenColorIO in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community
It works fine in editor viewport and does as well in game for about 30 seconds where it deactivates the display extension. It happens at the same time when the log spits out =“LogStreaming: Display: 0.190 ms for processing 9775 objects in RemoveUnreachableObjects(Queued=0, Async=0). Removed 0 (12529->12529) packages and 0 (283125->283125) public exports.”
So I figured some variable gets garbage collected, setting the in-game OpenColor IO display extension in various parts of the game or blueprints does not affect the issue.
