Retro Shaders Pro for Godot

A collection of PS1, N64, CRT, and VHS effects for Godot Engine. Step back into the golden age of gaming and faithfully add back the limitations of old tech into your games.

✨ Key Features

• PSX-style and N64-inspired shaders which emulate the look and feel of the classic games you love.
  • For the first time, combine the affine texture mapping of the PS1 with the three-point bilinear filtering of the N64!
• Lighting modes including unlit, standard lighting, and texel-aligned lighting.
• CRT and VHS post processing effect for an extra layer of retro goodness.
  • Plus a variant which can be applied to meshes, like an in-game TV screen.
• Skybox support for equirectangular and cubemap textures, plus a procedural cloud skybox.
• Hull Outline shader with a vertex snapping option.
• Demo scene listing all the features of the above shaders.

🎮 PSX Features

• Texel lighting which snaps shadows to the pixel grid of the texture on the object.
  • Adapted to work from this thread, especially user GreatestBear.
• A resolution limiter to automatically read lower texture mipmap levels.
• Vertex snapping modeled on the PS1's low precision vertex processing.
• Affine texture mapping to mimic the lack of perspective correction on PS1 hardware.
• Color depth limiter to reduce the color fidelity of objects.
• Dithering to smooth the transition between color bands.

📼 N64 Features

• Bilinear filtering using only three texels instead of the usual four (plus an option to use regular bilinear or nearest neighbor filtering).

📺 CRT & VHS Post Process Effect

• VHS-style effects: color damage, tracking artifacts, and worn tape effects.
• Barrel distortion to emulate the rounded screen of a CRT TV.
• Chromatic aberration to separate color channels at the edges.
• Pixelation to reduce screen resolution.
• Scanlines which can scroll across the image.
• RGB subpixel rendering which tints different pixels red, green, and blue.

✅ Compatible Versions

• This pack was created with Godot 4.5. Compatibility is only guaranteed on versions from 4.5 onwards.
• Works on all renderers (Forward Plus, Compatibility, Mobile), although texel-aligned shadows don't work properly on the Compatibility renderer.

Note: not all of the assets in the screenshots are available in this pack yet!
