How to disable the glowing of the doors?

[Googolplex]

Shaders like this are made to help a player find the exit, not to deliberately be "ugly". I personally liked the new shader, I'd rather not get frustrated from being lost and be helped, than worry about the glow of a door (though I can't see how someone could get lost in this game, so it may be a bit unnecessary). I'll see if I can find a way to disable it. Could be fun.

Thank you.
I don't understand how "easy" they wanted to make the game. It's never hard to find the exit, the glowing light really isn't needed. Will just ruin immersion for me.

I already removed the light, but as I said the problem is that notes also won't shine anymore.
