There already is a fuzz type in GZDoom called shadow but it behaves more like PrBoom+'s "Darken" fuzz type.

It's hardly necessary. I just personally thought it is the best middle ground of fuzz types, since it doesn't show the original sprite's colors but doesn't have noise.Caligari87 wrote:Could you describe why this is a necessary feature? I can see minor differences between these screenshots but hardly enough to warrant yet another fuzz type.
