how to make the Spot Light not shine all the time […] I don’t understand how to turn off the Spot Light glow in the game, only to make the glow be called by pressing the F key ?
Start with the component not being visible and then:
it turns out that the character’s hands light up
- either place it in front of the hands - the most convenient
- or you can try using channels:

If the light is on channel 0, meshes that ignore channel 0 will not be lit. But then you’ll need to consider how other lights behave as well.
