So i spent a day trying to fix this. Everything works fine in the editor, but if i build the game the shaders does not shown. Everything is black. I found a solution from this post's comments by yoyo: https://discussions.unity.com/t/shader-not-working-in-stand-alone-build-but-works-in-editor/14344
You have to have the Full Sebastian project Solar system folder in the "Resources" folder in order to work in the final build!
I hope this helps someone in the future, cheers!
