The complete PS1 look for URP: low-res rendering, vertex snapping, affine texture warping, dithered palette grading, ground fog and light halos. Add it to your camera, no art rework needed.Unity 6000.0+ with URP 17+. Retro Grade and Ground Fog are Scriptable Renderer Features built on the RenderGraph API, which does not exist in earlier URP versions. Built-in RP and HDRP are not supported. Ground Fog needs Depth Texture enabled on the URP Asset (on by default). Works with Forward and Forward+. A preconfigured URP Asset and Renderer ship with the demo scene.Retro PSX Stack recreates the 90s console look as a full stack rather than a single shader, because the look is not one effect. It is low render resolution, unstable geometry, warped textures and a limited palette all happening at once, and missing any one of them is why most attempts land somewhere between "modern game with a filter" and nothing at all.Every layer is independent and every parameter is exposed. Use the whole stack for a period-accurate PS1 game, or take one piece on its own - just the fog, just the resolution controller - and the rest of your setup is untouched. Values that would mean editing a shader elsewhere are sliders here: snap grid size, affine warp amount, palette levels, dither strength, fog height, density and drift, and render height anywhere from 120p to native.It suits retro horror above all, where a low resolution hides exactly what a flashlight should not reveal, but the same controls dial all the way down to a subtle grain for stylised shooters, PSX-flavoured racing, dream sequences, or a single flashback level inside an otherwise modern game.It works with whatever art you already have. The grade, fog and resolution passes are full-screen and need no changes to your meshes or materials. The PSXLit shader is optional, for when you want vertex snapping and affine warping on specific objects rather than everywhere.Includes a demo scene built entirely from primitives and procedural textures, a preconfigured URP Asset and Renderer so the effects are visible the moment you open it, an F9 live tuning panel, and full documentation with recommended values. No third-party content and no external dependencies.VFX INCLUDED (3 effects, 4 custom shaders)• Retro Grade - full-screen renderer feature: 8x8 ordered dithering, palette quantisation, shadow/highlight duotone, black crush, desaturation. Runs after post-processing so nothing blurs the dither pattern away.• Ground Fog - full-screen renderer feature: screen-space height fog reconstructed from depth with drifting procedural noise. Runs before post-processing so it grades and blooms with the scene.• Retro Resolution Controller - camera effect: renders at a low resolution and point-upscales, with optional 4:3 aspect lock and letterboxing, adjustable at runtime.• Lamp Glow - additive billboard light halos built entirely in the vertex shader, GPU instanced, with a component that writes only when brightness changes.CUSTOM SHADERS• PSXLit - vertex snapping to a configurable grid, per-vertex lighting, true affine texture mapping with a 0-1 blend. Forward and Forward+, SRP Batcher compatible.• RetroGrade, GroundFog, LampGlow - one shader per effect above.TEXTURES• 8 demo textures at 128x128 and 64x64, all generated procedurally. The effects themselves use no textures and ship no texture data.TECHNICAL• Built on the URP RenderGraph API. Unity 6000.0+, URP 17+. Not compatible with Built-in RP or HDRP.• Per-camera filtering on both full-screen effects (main camera only, all game cameras, explicit list, or exclude list) so secondary cameras rendering to a RenderTexture stay clean.• F9 runtime tuning panel with every parameter as a slider. No input package dependency, works on either input backend.• Assembly definitions for Runtime and Demo. The Demo folder can be deleted entirely.• Demo scene: 128 renderers, all Unity primitives.• No external dependencies, no third-party content, zero compile errors and no deprecated API warnings.
