VSPT

Features

VSPT traces the path light takes through the world, from the sun or a torch, off whatever it hits, to your eye. These are the things that changes. Each picture is a moment from the gallery: hover over it to see the same moment in the unmodded game, or click to compare them side by side.

Vanilla

Light from real sources

Every torch, lantern, oil lamp, candle, campfire and pool of lava is a real light. It reaches what it can see and nothing else, so a cave stays dark until you bring a light into it, and a torch lights the rock around it, warm and flickering.

VSPT handles many lights at once, so a hall full of torches works as well as a single one. Light colour, on the Materials page, sets how warm the flames are.

Vanilla

Sunlight that bounces

The sun and the sky light the world, and the light keeps going: off a sunlit floor onto the ceiling, off a bright wall into the shade beside it. Shadows soften with their distance from what casts them.

The quality presets trace one bounce on Low and up to four on Ultra.

Vanilla

Water

The sea moves in real waves, with foam and whitecaps, and boats ride the swell and leave a wake. It takes its colour from the local climate, bluer and clearer offshore.

Sunlight through the surface throws caustics on the bed below, and the surface reflects the sky and the shore.

Vanilla

Reflections and glass

Water, metal, polished stone and glass reflect what is really around them, including what is behind you or off the screen.

Glass bends the light that goes through it. Coloured glass tints by its thickness, frosted glass blurs what is behind it, and opal and milk glass glow when light shines through them.

Vanilla

Materials, texel by texel

About 9,000 of the game's textures have hand-made maps for relief, roughness, metal and glow, at the game's own pixel size. Ore glints in the rock, metal shines, soil stays matte, and the pixel art stays pixel art.

Blocks from other mods get a sensible material on their own, and modders can give theirs better ones with the guides.

Vanilla

Fire and hot metal

Hot metal glows the way hot metal does: dull red at 600 °C, cherry red at 900 °C, white at 1,500 °C, in the forge, on the anvil and in your hand. Its light falls on everything around it.

Embers and smithing sparks light what they fly past.

Vanilla

Clouds, fog and weather

Volumetric clouds are lit by the sun and cast their shadows on the land, and they can reach all the way to the horizon.

Fog is traced too, so the sun throws shafts of light through it. Rain, lightning and puddles are part of the traced world.

Vanilla

Night

Nights are dark, lit by the moon and the stars, and the aurora ripples across the sky in the cold north.

The view adapts to the dark over a second or so, as your eyes do.

Vanilla

Land to the horizon

With Far terrain on, the land past the loaded chunks reaches out as far as 8,192 blocks, read from Algernon's Terrain Sampler, and World curvature bends it down towards the horizon.

Far terrain works in single player for now.

Vanilla

HDR from the first ray

VSPT works in HDR from the first ray to the last. On an HDR display the sun, flames and highlights go brighter than white; on an SDR display the same picture is fitted to it.

Tone mapping has four curves (Standard, GT7, Filmic and AgX), and the Vanilla look slider brings back as much of the game art's own colour as you like.

And more

Fast enough to play

DLSS Ray Reconstruction turns the few rays traced each frame into a clean picture. On Windows, frame generation and Reflex keep it smooth: DLSS on RTX 40 and 50 cards, up to 4x on the 50 series, or AMD FSR 3 on any RTX card. Presets go from Low to Ultra.

Photo mode

F12 holds the world still while you frame a shot with depth of field, then saves it as an HDR photo. Every shot in the gallery was taken with it.

One mod to install

Install VSPT from the Mod DB. Its setup, in the game, installs the rest, patches the game and keeps it all up to date.

Works with your mods

Most mods work as they are, their blocks, creatures and items traced like the game's own. The FAQ lists the ones known to need something.

Windows and Linux

On Windows 10 and 11, and on Linux with NVIDIA's own driver, with HDR on a Wayland desktop.

Every setting and message is in all of the languages the game offers.
