So I went to Show → Visualize → Preview Shadows Indicator, and turned it off. When I’m editing it’s gone, and that’s great, but when I press the play button, it’s back. Any ways to fix this?
Build your light and the preview is gone in editor and ingame.
Or change the light source causing it to Movable if wanted.
when I publish and play the game with the .exe file and stuff will it be gone?
Once you have build light yes, otherwise no.
