Fast Flat Shader

FAST FLAT SHADER - FULLY CUSTOMIZABLE RETRO FLAT-SHADING SYSTEM

Turn any scene into 1st generation polygon arcade graphics with one fully customizable URP post-process effect. Whether you're chasing an authentic 1993 arcade look or your own stylized retro creation, this pack gives you full control over every detail. 

HOW TO USE:

Add the Fast Flat Shader Renderer Feature to your URP renderer, then drop any of the six ready-made Volume Profiles onto a Volume - instant 1993, on any scene, any mesh, with zero content changes.

Alternatively, tweak the Fast Flat Shader Volume override to design a custom look, or blend local Volumes for per-area styles - retro arcade in one room, modern rendering in the next. The showcase scene does exactly that.

EASY TO CUSTOMIZE:

Create the perfect retro look for your scene using the exposed Volume parameters:

Six Showcase Looks - Start from the full Master profile, or from LowRes, Facets, Toon, Dithered, or Sunset - one Volume Profile per signature feature.

Pixel Scale - Square-pixel snap to any virtual resolution for that chunky arcade-monitor feel.

Facet Relighting - Lattice-quantized normals re-light the scene as flat polygons - any mesh reads low-poly, no remodeling.

Light & Color Grade - Aim the key light and tint light/ambient colors for full evening-arena style grades, then dial in Saturation and Output Gamma.

Toon Banding - Optional Shade Steps for clean banded cel shading.

Color Crunch - Albedo posterize plus optional 8x8 ordered dither for the classic 90s color crunch.

Every Feature Can Be Tuned - 13 named parameters on a single Volume component, one lean fullscreen pass, built for runtime tweaking and smooth per-volume blending.

The master Shader Graph is fully documented, with a cleanly organized graph making it easy to modify, expand, and build your own custom looks.

Auto-Playing Camera Tour. Press Play and the gallery presents itself.
