So i have a space scene with Earth in the middle. I created a custom sky sphere where i placed my stars background. So far so good. The only problem i have is that i lost the sun represented by the directional light. And i really want that to be present in the scene (logically, since it is a space scene you want the sun to be there…). So, how to make the sun position visible? Is there any option im missing? maybe the sun position is too far away (and its drawing outside the sky sphere)?. Thanks in advance.
Bumping this because i still didnt find a solution. Is custom skyspheres not compatible with showing up the sun from the directional light?
I am also looking for a solution. I used to import a .dds cubemap before and threw that in the blueprint, but the next time I loaded the project it was all messed up. I am now using an actual sphere of 1000,1000,1000 scale and all my components are inside of it. I think you have a similar setup? I tried removing the directional light and make a singular massive spotlight, but that would cause the lighting to not build. A directional light doesn’t light anything up (all objects turn black). I assume this is because it is outside of my sphere, and the sphere blocks it.Have you found a solution to this yet? I would love to know it 
(If I find a solution myself, I will let you know)
Hi amstradcpcuser,
If you are still looking for help with this, would you mind providing your project for download so that I can investigate?
Yup, my sky sphere is supossed to hold everything in my scene. I dont know for sure the size, but well, it is a skysphere lol. Using a spot light is out of the question because im also using postprocess effects, meaning that for example im using lens flares and i cant achieve a realistic result with a spotlight lol. Maybe in your case is different, but in mine the sun is essential.
In my case, the directional light works pretty nicely (it is a space scene so you will just see one side of the earth lighted up, as it should be) but actually im pretty sure it is INSIDE my skysphere.
Anyways, i parked this project time ago because well, i couldnt find a solution and i just dont want to do things in half measures. If someday i see a tutorial or someone enlightengs me, i will continue. One could have hped that in the UNREAL forums you will find some advise or a solution… oh well.
Hello! Maybe for some people this will help;
When using directional light with a custom Sky Sphere blueprint, if you still want the sun from the directional light, go to your Sky Sphere details pannel and under “default” change the “Directional Light Actor” to “Light Source”.
