Although this plugin works great, my only complaint is the blinking stars, that looks very unnatural, looking more like Christmas lights than stars. Couldn’t find anything on the web about this. Tried to tweak things, but couldn’t manage to stop the blinking.
I managed to find the exact node that makes the stars blink in the skybox blueprint (M_24hrSky), which is the “Time” node. Just set the “Period” parameter to 0. The only problem is that the stars are regenerated whenever you move the camera, making it a pretty ugly sky unless you stay completely still.
I think it’s more worth it to just make my own day-night cycle, as it’s not that hard.
