I am making an Among Us clone with multiplayer, and I'm a little stuck at recreating the lighting effect around the players. Heres what I have right now: 
I'm getting this weird whitish color on the slave players on each client. These are my options for the CanvasShader on each player's AnimatedSprite Node, it shows Light mode as normal but I change it to "light only" during runtime for slave players so that the master player(the player each client controls) doesn't get affected by the light.

Why does this happen and how can I fix this?
Edit:
All my project files and code are available here if anyone would like to see something else https://github.com/MysteryCoder456/AmongUsRemake
