2.0 Update for Advanced CRT Shader
Advanced CRT Shader for GameMaker » Devlog



I've refactored the code to improve performance and greatly enhance the realism of the CRT effect (see images).
- Added the ability to capture user-specified draw events and include them on the CRT screen, fixing the GUI sizing issue some users were reporting.
- Ensured that all blending operations are now gamma-correct, improving color accuracy and playing more nicely with HDR.
- Took phosphor masks back to the drawing board and came up with a much more flexible solution requiring fewer textures.
- Added beam dynamics, adjusting the size and shape of scanlines depending on the energy of the beam.
- Reworked the reflective screen border, allowing users to customize its size and material properties.

Hi, I'm curious which shader language you wrote this in, GLSL ES? Thanks
