Hello prolenorm,
Thanks for purchasing the plugin and I’m glad to hear it is helping you out! Someone else has reported the issue of atmospheric fog being captured. Unfortunately, it is a known bug that fog is being captured by SceneCaptureComponents, even if you add the fog actor to the Hidden Actors list:
I have already looked into the fog issue. I have tried disabling the SceneCaptureComponent’s Fog ShowFlag as Andrew Hurley suggested as a workaround in that AnswerHub post, but while it did hide fog in pixels that show the sky, it didn’t affect pixels that contain geometry. I have tried finding other workarounds for this, but at the moment I think this is a bug that can’t be addressed without modifying engine code. The best you can do at the moment is temporarily disable fog, generate a snapshot and save it to a texture. And vote for this issue perhaps to let Epic know that it is affecting you:
