Is anyone aware of a way to toggle a greyscale effect to the entire screen of a player? I want the player's screen to be black-and-white while they are dead and waiting to respawn in this project, but everything I've found so far has just been about greyscale to individual icons, but I want things to remain in color for everyone else.

You'll want to use
client.color

Something along the lines of:

client.color = list(0.30,0.30,0.30,0, 0.60,0.60,0.60,0, 0.10,0.10,0.10,0, 0,0,0,1, 0,0,0,0)


Should do it, but I can't easily test it. Check out this topic for more information on color matrices.
The exact values are the arguments in the grayscale example for icon.MapColors(), except you put them in a list for client.color (or a plane master).
Thanks so much, this works perfectly!
