Thanks for the fast response! I'm asking if its possible to directly distort the image without duplicating what's behind and then distorting that duplicate image. Like this!: Your shader distorts the image but keeps what's behind unaffected so you can see what's being distorted behind like this: So, as you can see the difference is that in yours the effect applies over a duplicate of what's behind and you can see both, the distorted image and behind the unaffected image (wow is really hard for me to explain this haha, sorry, I'm not english speaker). And in the example that I mentioned above the distortion effect fully affects the image and you can't see how it look without being distorted. I'm asking this because I would love to have an effect that does this. I want to re-create a black hole distortion, and so far with the distortion shader I have good results, but not as inteded because it doesn't fully distort the image. Take a look: I think I know how to explain it. -> I don't want to see through the distortion and be able to see how it look non-distorted behind the effect, I want the distortion to be more or less powerful based on the opacity, but not be able to see through, to achieve this: Maybe there is a workaround that I'm not seeing. [EDIT]: I just noticed that in your shader there is a slider bar for opacity that goes from 0 to 2. Default is 1, so that's why you could see through the distortion, is that how it works? and then there is a slider labeled "distortion" that in your prefabs goes from 0, 10, 100... ...up to 1000, is there a way to control that via the particle shuriken as the alpha?. But anyways, is there a way to achieve what you can see in the image above, the black hole? I'm using the default particle sprite as distortion, maybe another sprite could achieve this effect. Thank your for the fast support by the way! [EDIT]: I reached something similar using a simple circle fading from white to black in photoshop, but the effect is resolution dependant. When I use the 16:9 aspect ratio in my game view (because the window is little it looks like this: But if I force always 1920 x 1080 the effect is reduced like this: Thanks again, I hope you could answer the whole thread post haha. Sorry for it being so long! I still want to know if I can achieve full distortion without transparency.
