I’ve asked this before on this forum and a few subreddits but got nothing. Seems like it’s just completely impossible at the moment, but this would be HUGE for a lot of people out there.
Lumen is the only way I can make cinematics in unreal for now because of the lack of volume materials which play a big role in lighting, fog, ambience, etc. It would be unbelievable if the accurate shading and lighting of path tracing could be combined with compatibility of Lumen.
Here’s an example of what happens when you turn path tracing on with a volume material in the scene; unreal just completely ignores it.
