How do you make a billboard sprite unlit?

Hey! Thanks for responding. I’ll take a look at the shader nodes. What I am wanting if for the sprite to be dark in dark environments. Like a dark room. The problem I am running into is that even without any lights the billboards are lit and seeable. The non billboard sprites are fine. They have translucent unlit sprite material attached and are unseeable without a light being used (the player is given a flashlight). Any other thoughts is super appreciated.
