OpenColorIO In-Game bug

[EpsilonIsHere]

Hi everyone,

I’d like to use OpenColorIO (OCIO) for color management. It works as expected in the viewport and likely functions correctly in the Movie Render Queue as well (though I haven’t tested that yet, as I don’t need it at the moment).

However, I’ve encountered an issue when trying to use it in in-game or Play in Editor (PIE) mode. Specifically, it works initially but gets disabled after approximately 50 seconds (anywhere between 0-60 seconds, to be honest).

Has anyone experienced a similar issue with OCIO? Could it be related to the plugin itself, or possibly an engine bug?

For context, I’m using the Create In-Game OpenColorIO Display Extension node and attaching it to the Event BeginPlay. I’ve also tried removing and re-adding it periodically, but the same thing happens.

Thanks in advance for your help!

So, I figured it out…

The OCIO Display Extension gets destroyed by the garbage collector.

Solution: To prevent this, we need to store it in a variable:

1. Create a new variable of type OpenColorIO Display Extension Wrapper.
   

   

2. Initialize the OCIO Display Extension and assign it to this variable.
