hello,
I’m sorry to hear the effect isn’t working for you. Are you trying to add it to an existing game? Does it at least work in the example project? If the example project doesn’t work, then you may need to update GameMaker or your video drivers.

Yeah, the example project works. I'm not sure what I'm doing wrong. No matter which preset object I put in my room, the screen just goes all black. I'm making sure to put it in the first(and only) room in my game and it's first in the instance order.
EDIT: Just had to change the aspect ratio and game_width and height in the variable defs for the preset, working great now. Thank you
