so i was just doing some work on my game when i noticed that the skybox i added a while back just suddenly broke, it doesn’t show eccept through the terrain.
Seems like the creator of the skybox you’re using opted to leave the Skybox Face properties empty (aka the textures for the skybox are missing). This results in a pure black sky, but then Roblox ends up using a fallback texture for anything that samples the skybox textures (reflections and Atmosphere fog), which results in the weird grey look.
To fix this, I would simply go to your Sky instance, then fill all the SkyboxFace properties with a black texture (you can make one yourself or use one from the toolbox)
