Vertex-colored & Vertex-lit Shaders (N64/GC/DS/PS1/PS2 style)

Overview

This is a collection of shaders I use to replicate the look of Nintendo 64 models and sprites. Unlike the standard PBR shaders, these shaders use per-vertex lighting, support vertex colors, and emulate the N64 and PS1 texture filtering styles.

Vertex lighting vs per-pixel lighting comparison

List of shaders included

• Vertex-lit & Vertex-colored/
• Opaque/
• Dual texture: Allows you to transition between two different textures on the same model, with vertex lighting. I used this on the ground tiles in a digging game to transition between the default state and the "dug" state.
• Sphere mapped: Fake environmental reflections (Metal Mario effect).
• Vertex-lit Alpha Blend: Overlays a texture and a color (optional) on top of a model's vertex colors, with smooth edges.
• Vertex-lit Alpha Clip: Overlays a texture and a color (optional) on top of a model's vertex colors, with pixelated edges.
• Vertex-lit Modulate: Tints a texture with a model's vertex colors in multiply mode.
• Transparent/
• Alpha Blend: Displays a transparent texture with smooth edges.
• Alpha Clip: Displays a transparent texture with pixelated edges.
• Billboard Alpha Blend: Renders a sprite as a billboard (always faces the camera) with alpha blending. Great for Bomberman/Smash style item pickups.
• Billboard Alpha Clip: Same as above, with pixelated edges.
• Animated Billboard Alpha Blend: Plays an animation from a sprite sheet as a billboard with smooth edges.
• Animated Billboard Alpha Clip: Plays an animation from a sprite sheet as a billboard with pixelated edges.
