I really try to use one shader in postprocess volume for lens distortion (https://vimeo.com/107285823) without success…
Then i follow The unreal Post Process Material doc (Post Process Materials | Unreal Engine Documentation) and made the exact same shader.
When i apply to post process volume (blendables), the screen turns grey (semi-transparent). - same with the first shader…
someone could help? or this is a bug?
tks
