Can you post a screenshot of the SkyAtmosphere settings (with all advanced settings too, from clicking the dropdown arrow to display them)?
There’s at least some difference between the SunSky actor and placing each component in it in the scene, separate from having a SunSky actor. One major difference is the compass and lat/long system, and another is how the SkyAtmosphere settings getting modified causes changes in the lighting and visibility / look of the sky. Overall, the two methods are similar, though. More information is needed to get a better idea how to help fix that strange sun problem. So, providing SkyAtmosphere settings in a screenshot, and some settings of the directional and skylight would really help. I honestly don’t know exactly how to create a moon disc, but have seen a video or two that contain instructions for how to do it, I think, which were on youtube and/or in the docs / learning area of the Unreal site. If you really want to understand how to do it, it’s better to research it in-depth rather than waiting for a developer to do a whole write-up of it in the forums.
