K-CRT is an add-on that applies a retro television screen effect to your renders. It provides a customizable CRT shader that replicates the appearance of vintage displays.

The tool includes controls to adjust the position, rotation, and scale of the main RGB texture. You can modify the grain effect by changing its location, scale, randomness, and detail level, which can be useful when animating the texture. An emission strength parameter controls the intensity of the shader's glow, which is optimized for the Cycles render engine.
