Retro Shaders Pro for Unity URP

This pack adds new shaders, scripts, and meshes to Unity, complete with a demo scene showing them all off. The shaders emulate the graphical style of 3D consoles from the 90s.

✨ Key features

• PSX-style and N64-style effects which emulate the look and feel of classic games.
  • Blend together the limitations of both consoles for the first time!
• Lit, Texel Lit, Vertex Lit, and Unlit shading models which you can easily toggle per-material.
  • With full support for transparency, face culling, and alpha clipping.
• Terrain support with the Terrain lit shader.
• Skybox support for cubemap textures and procedural clouds.
• Shader Graph copies of the core shader which you can freely edit or copy.
• Decal shader which supports most of the retro features.
• Hull Outline shader with vertex snapping option.
• Two demo scenes:
  • A wooded area focusing on terrains and direction light support, with trees, mushrooms, and geese.
  • A city block showcasing additional spot light support, with buildings and street lamps.

🎮 PSX-style Features

• Texel lighting which snaps shadows to each object's texture.
  • Adapted from work in this thread, especially by user GreatestBear.
• A resolution limiter to automatically use lower mip levels for your textures.
• Vertex snapping modelled after the low precision of the PS1's vertex processing.
• Affine texture mapping to mimic the lack of perspective correction on the PS1 hardware.
• Color depth limiter to reduce the color fidelity of your objects.
• Dithering in screen space or texture space blend between color bands.
• Specular Lighting with a glossiness option per-material.
• Cubemap support for PSX-like metallic reflections.
• Framerate limiter script.

📼 N64-style Features

• Limited bilinear filtering, which uses three texels instead of the usual four.

⚡ Lighting & Rendering Features

• Support for Forward, Forward+, and Deferred rendering paths.
• Directional light and additional light support in Lit & VertexLit.
• Ambient light controls - override Unity's ambient light.
• Seamlessly pick between Lit, Texel Lit, Vertex Lit and Unlit lighting models, all in one main shader.

📺 CRT & VHS Post Process Effect

• VHS-style effects: color damage, tracking artifacts, and worn tape effects.
• Barrel distortion to emulate the rounded face of a CRT screen.
• Chromatic aberration to separate the color channels towards the edges of the screen.
• Pixelation to reduce the screen resolution.
• A scanline effect which scrolls down the image.
• An RGB subpixel rendering effect which tints different pixels red, green, or blue.
• Interlaced rendering to alternate between rendering different rows of pixels between frames.

✔️ Compatible Versions

• Compatible with the Universal Render Pipeline only.
• Fully tested with Unity 2022.3, 6.0, 6.1, 6.2, and 6.3.
• Please note that this package was designed for desktop use. Support is not guaranteed on VR, mobile, or console platforms.
