Hello I’m Newbie here… I want to ask something… when i clicked my object suddenly unknow sphere appear, but when i clicked other stuff the sphere gone. Actually it’s not a big deal because when i play the game the sphere doesn’t appear , but still it bothering me…
That looks like a light probe. It’s an editor indicator to show you how the precomputed global illumination will be processed. The lighting/shading on the sphere is indicative of how dynamic objects in that vicinity will be lit.
