- Description:
- The CRT Filter for URP & PixelPerfect is a high-performance, easy-to-configure shader that can be used in Unity projects. It is preconfigured for the Universal Render Pipeline (URP) but can also be used as a standalone shader. The filter is designed to create many CRT 'artifacts' and can be adjusted to suit different project needs.
The filter has a wide range of parameters that can be adjusted from 0 to 100%, with 0% effectively turning off the parameter. The supported parameters include:
* Screen bend and overscan to simulate CRT curvature
* High-performance blur effect
* Pixel bleed to simulate phosphor and beam glow
* Pixel smidge - subtle effect that bleeds high luminous pixel on edges vertically
* Scanlines and aperture lines
* Animated shadow (interference) lines (horizontal or vertical)
* Animated noise
* Vignette
* Chromatic aberration with custom settings
* Brightness / contrast / gamma settings
* Individual R G B settings for under or over saturation
The filter uses a single-pass shader, which creates little to no performance impact. An alternate lite version of the shader is also provided for mobile devices or devices without a GPU.
The filter is suitable for any type of game, but is especially suited for pixel art, as it makes each individual pixel look more natural. It can be used in many project configurations, but was designed for URP with PixelPerfectCamera component.
The filter works in many project configurations, but was designed for URP with PixelPerfectCamera component. For more information, see the technical details below.

- The CRTFilter was designed for URP (Universal Render Pipeline) and ideally with the PixelPerfectCamera component with enabled crop (any value except 'none'). The PixelPerfectCamera component provides a fixed target resolution independent of the real resolution of the user's device, allowing CRTFilter to properly align all pixel-based effects to individual pixels, resulting in the intended image quality. However, these effects would still work even without PixelPerfectCamera or outside URP, just the pixel alignment may be off. This misalignment would be visible on full screen with 'pixelated graphics', but is acceptable for high-res graphics or if the filter is used on in-game monitors (also in 3D games). The filter works with standard post-processing and is placed in the render pipeline based on selected injection point. The filter is added as a Renderer Feature to a renderer, allowing it to be used either as a fullscreen effect (applied to a main camera) or to create CRT effect on in-game monitors (rendered by a separate camera).
