When setting a SceneCapture with Capture Every Frame set to False, the capture will appear bright green in Packaged project. It captures as expected in editor/ PIE, and also works fine if Capture Every Frame is set to True. This issue occurs in 4.17 and 4.18.
I can work around it by having a delay in my game mode and then force re-capturing all scene captures, that works, but is obviously not intended and pretty hacky... so figured this should really be reported properly.
To reproduce, I suppose all you have to do is place a scene capture (I'm using a scene capture cube), use it in a material, then put it in a map and package the project (I use shipping config). Im just using the launcher version of 4.18.1.
