i setup six spotlights around a sphere to light some objects in the sphere,
i turn off cast shadow, when i preview VR in the editor, all lights work fine, but after i build the project, and launch from the standalone exe, strange thing happened, all spotlights disappear !
After some research, i finally catch the issue, the key point is cast shadow option, if i turn on the option, all spotlight work good, if i turn off the option, all spotlight gone ! This only happen in the standalone mode not in the editor !
