Godot PSX Style Demo

Available on GitHub (MIT License)

A collection of shaders and materials for Godot engine that aim to recreate the following aspects of the PS1 aesthetic:

• Vertex "snapping"
• "Wobbly" texures through affine texture mapping
• 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 rotation

Tips for best results

• Use low poly models
  • Prefer smooth-shading over flat-shading wherever possible
  • Don't be afraid to include extra edge loops to smooth out texture distortion in your geometry! PS1 levels often had much higher polycounts than you might expect!
• Keep textures as low resolution as you can
  • Make sure filtering and mip-maps are both disabled
  • Rely on a mix of vertex colours and texture maps, instead of higher detailed texture maps wherever possible
  • Posterizing your textures with a depth of 15 or 16 before import goes a long way to making them feel more "PS1"
• Keep your internal resolution low
  • Common PS1 resolutions were 256×240, 320x240 and 512x240 (Source)
  • 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
