Problem with CRT effect

Welcome to our brand new Clickteam Community Hub! We hope you will enjoy using the new features, which we will be further expanding in the coming months.

A few features including Passport are unavailable initially whilst we monitor stability of the new platform, we hope to bring these online very soon. Small issues will crop up following the import from our old system, including some message formatting, translation accuracy and other things.

Thank you for your patience whilst we've worked on this and we look forward to more exciting community developments soon!

  • Hi everyone, I'm looking to make a CRT effect for my new game and I came across a thread on this forum that had a pretty cool looking shader that did just that. You can download the shader from the thread in the link bellow.

    However I keep getting these really nasty looking bulging bands across the screen. Example screenshot below. Anyone have any idea what might be causing this, or how I might fix it? What's shown in the picture is the shader with all atributes on default. But I've tried playing around with the settings and I can't seem to get it to look good. Any help would be appreciated.

  • I don't have an answer for your specific problem, but if you can't make this shader work you can always make a scan-line effect easily by placing a layer on top of everything and having a Quick Backdrop containing an image of 2 contrasting gray (and semi-transparent) 1 pixel tall horizontal lines. I used this for a Flash game and it worked perfectly, let me know if you need more details. Cheers!
