How to Add a Material to a Lamp in the Blender Game Engine I'm making a game in UPBGE mainly it has a day/night cycle. I made a street lamp with a spotlight. I'm asking for a way to use nodes in for the lamps in the game engine.
If you're still trying to do this, or if someone else is trying to, you can animate the brightness of the spotlight and use logic bricks (or python) to play that animation.
