~ SittingDuck's CRT shader ~
A robust and flexible CRT shader that aims to be scalable and easy to implement.
Out of the box features include:
| Scanlines | Curvature | RGB phosphor emulation | Bezel reflections | Automatic resolution and aspect ratio handling | Interlacing | Integer scaling | Halation, glow, and bleeding effects | Support for portrait (TATE) mode | Support for bezel overlays
To implement with your existing game, place a preset object in the first room of your game or create & destroy one via code in your game's menu. Ensure that your game's aspect ratio matches that of the preset object. That's it!
Advanced use:
All parameters of the shader are addressable from any object just by referencing the crt object. For example: "crt.glow_amount += 0.1". Just make sure to update the shader uniforms afterward with "crt.update_uniforms()"
Learn to use effects that retro game developers used with CRT TVs in mind; exploit interlacing, blending, or phosphor glow for your game's benefit!
Detailed documentation and a working example project are included to quickly get your project up and running!
