Ultimate Retro Shader Collection

A compilation of shaders designed to replicate the graphical style of the PlayStation and Nintendo 64 in the Godot engine.

---

📋 Overview

Ultimate Retro Shader Collection (URSC) is a unification and enhancement of various "retro-3D" shaders sourced from the Godot community. These shaders are essential for creating authentic graphics reminiscent of the PlayStation (PSX) or Nintendo 64 (N64).

This repository is home to the collection itself and an interactive demo. You can download the collection as a standalone zip file or get the demo executable by visiting Releases. URSC also has an itch.io page with downloads and a browser-playable version of the demo!

Shader Features:

• Vertex snapping (a.k.a. vertex jitter)
• Affine texture mapping (a.k.a. texture warping)
• 3-point texture filtering (as seen on N64)
• Distance-based texture LOD (as seen in some PSX games) (1.2.0+)
• Special "metallic/reflective" and "shiny/glossy" effects
• Basic customization through a wide range of uniforms
• Detailed customization with macros
• Bonus shaders:
  • PSX-like additive/subtractive fade
  • Color reduction with dithering
  • Single-image, flat sky (1.2.0+)
• Support for all rendering methods (Forward+, Mobile, and Compatibility) (1.1.0+)

Demo Features:

• A variety of samples
• Two camera modes: orbit and free
• Control shader parameters through the menu
• Background music

Demo Controls:

• Toggle fullscreen: F11 or alt + enter (option + enter on macOS)
• Toggle menu: escape
• In free mode:
  • Move: WASD; space or E to move up; shift or Q to move down
  • Change movement speed: mouse wheel up/down
• In orbit mode:
  • Toggle orbit: space
  • Reverse orbit direction: shift

Demo Version Differences:

• The web version:
  • uses the Compatibility rendering method.
  • only supports the orbit camera mode (all controls for this mode are available).
  • does not support the above controls for toggling fullscreen. To toggle fullscreen, you must use your browser's provided controls. On Itch, a button to enable fullscreen is provided.
  • does not support the above control for toggling the menu.

😎 Credits

Of course, this collection would not've been possible without the amazing work done by:

• MenacingMecha
  • This collection derives from his PSX and N64 shaders. If you need inspiration for creating your own retro-3D game, definitely have a look at his work!
• Zacksly
  • The "shiny" effect comes from their PSX Pickup Shader for Godot 3.
• tentabrobpy
  • The "flat sky" effect was adapted from their shader on Godot Shaders.
