I've been having some issues with versioning on the Marketplace, I recommend you get this from instead.
NOTE: The GMS 1.4 version was not, and will not be updated. Please switch to GMS2!

bktGlitch is a glitch shader with a variety of unique layered effects that will break your game... in a good way.

Free as of June 2020!



  • Effects such as tearing, noise, colour dispersion, glitch blocks, RGB splitting...
  • Written in GLSL ES - not limited to desktop platforms!
  • Easy-to-use setup scripts and presets, no need to set up uniforms manually!
  • A demo where you can adjust all effects manually and even generate the resulting configuration code!

If you end up using this, a credit would be appreciated.
