The look of the game I am making is very depended on several effects (bulge, pixellate, RGB channel separation, and VHS damage) But I only want these effects to be applied to certain layers. When I apply the effects to all the different layers of my project separately, the framerate suffers. But when I apply all the effects to the layout instead, the game runs smoothly.
I just want to know if there is any way that I can, either apply one effect to multiple layers, make one layer "Immune" to effects, or some other workaround that keeps a steady framerate.
