I found that it's ok in a Landscape. However, it doesn't has any effect in a Portrait

Alright, I think I know what is going on: The vignette is computed using the aspect ratio width / height. In landscape, this is > 1 giving the expected result, but in portrait it does not. You can try to play around with the radius parameter (and maybe up the opacity) to see if that changes anything. In any case, I will update the shader to detect whether the format is landscape or portrait.

Good find!
