A collection of shaders and materials for Godot engine that aim to recreate the aesthetics and quirks of the N64

![Example Screenshot](./readme-assets/screenshot.png)

## Features

- 3-point texture filtering

- Light anti-aliasing

- Linear mip-map filtering

- Horizontal blur across the screen

- Limited color depth

- Hardware dithering to hide color banding

- Shiny chrome-like metallic surfaces

- Billboard sprites

- Fog to limit draw distance

## Demo Controls

- Space: Toggle camera and object movement

- R: Reset scene

## Tips for best results

- Use very low poly models

    - Prefer smooth-shading over flat-shading wherever possible

- Keep textures as low resolution as humanly possible

    - Huge blurry texels are the cornerstone of the N64 look

    - Rely on a mix of vertex colours and texture maps, instead of higher detailed texture maps wherever possible

- Keep your internal resolution low

    - Resolution on N64 is a complicated affair. While the system would output to video at certain specific resolutions, games themselves would have their own separate internal resolutions

    - These internal resolutions could vary wildly between games, but 320x240 seems to be the most common choice

    - That being said, you can easily go widescreen by using a 16:9 resolution with similar height

- Use as basic of a lighting set up as you can get away with

    - Modern lighting techniques are a very easy way to break the illusion of appearing like early 3D!

    - Where possible, prefer to use white ambient light, with vertex colours on geometry to fake lighting

- Prefer additive blending to transparent blending

## Changes from v1.x

### Major version change

This version is for Godot 4.x only.

Please refer to the v1.x branch for Godot 3.x support.

### Fog

Godot 4.0 changed how environmental fog worked, the key part being the removal of the "start distance" and "end distance" properties.

While a manual workaround could be implemented, there is work being done to restore this functionality in a later version.

### Runtime options

In order to release working Godot 4 shaders as soon as possible, runtime options for the demo will be re-implemented at a later date.
