PS1-style 3D for Godot 4 and Unity, free. Wobbling vertices, warping textures and 240 chunky lines over your own level in one line:

var psx := PSXScreen.new()
add_child(psx)
psx.viewport.add_child(level)
PSX.convert(level)   # every StandardMaterial3D becomes its PS1 version

Want more?

PSX Look adds the PS1's 15-bit colour and its 4x4 dither on PSXScreen, and four more materials: unlit, cutout for foliage and fences, transparent for water and glass, and sphere-mapped chrome. Same code: install it over this one.

What's inside

• Vertex snap: vertices land on the low-res pixel grid, so edges jitter as the camera moves.
• Affine texture mapping: textures warp across big polygons as the PS1's did. A slider blends back to perspective-correct.
• PSXScreen: renders at 240 lines (or 480, or any), scaled up in sharp square pixels. UI outside it stays crisp.
• The lit material (per-vertex lighting, nearest-filtered textures, vertex colours, UV scrolling) and PSX.convert, which turns an imported level's StandardMaterial3Ds into it.
• Demo: a ruined courtyard at dusk with torches and 9 PS1-style textures. Walk it right here in the browser.
