No Speed Lines and Space Particles
This simple mod removes the rainbow lines when using boost and pulse in space. It also removes those fluffy little particles floating around up there when you aren't boosting or pulsing. You can choose one or both, all included in one .zip file.
PS If you wish to ask a question it will have to be done through this mods No Man's Sky Nexus page. Sorry. I don't use social media.
Place the .pak you choose into the games PCBANKS folder and delete the SHADERCACHE folder. Start game.
