For Real

5.0 is the biggest engine release Spawn has ever shipped. The theme, if it has one: your world got real. The sky scatters actual sunlight and hands over to a moon at night, the ground has depth you can see and edit instantly, enemies can genuinely find you, and multiplayer runs on a new engine — with matchmaking your game controls. Nothing here needs migration: your game stays on the engine it was built with until you take the update — ask Savi, or hit the "New features" button in the project tab — and when you do, it keeps working exactly as written: much of this turns on the moment you update, and the rest is one flag or one sentence to Savi away.

Storms, explosions, magic — a million particles. Effects used to hit a hard ceiling around twenty thousand particles; now the graphics card runs them itself.

• Ask Savi for a snowstorm you can stand inside and she builds it — over a million particles without slowing down. The nebula in the clip below is about half a million motes you can walk through.
• Effects carry real light: a campfire genuinely warms the cave around it, an explosion flashes the walls.
• When Savi invents a brand-new effect mid-conversation, it appears the same instant — no shader compilation, no stutter.
• Ask her for smoke that darkens the room instead of glowing and she has the tool: a new subtract blend mode for particles and sprites — smoke shadows, ink clouds, energy drains.
• Glow, smoke, and fog finally play fair: bright glows always draw on top of smoke, overlapping smoke puffs sort properly instead of flickering, and distant fire keeps its color in fog instead of turning gray. Effects using the old screen blend now render as additive glow, which behaves correctly on bright scenes.

Every light you place actually lights the world.

• Streetlights, neon signs, lanterns, torches — hundreds at once (our test scene runs roughly 950) instead of only the few nearest the camera, and the lighting no longer shifts when you turn around.
• The sky now gives your world soft ambient light when you haven't set your own, so outdoor scenes stop looking dim — blue-tinted by day, warm at sunset, dark at night.
• Sun shadows are steadier (no more flickering while nothing moves) and reach farther into the distance, and the engine picks lighting quality to match each player's device, so big lighting setups stay smooth on phones.
• Point a spotlight at something by saying where: light: { kind: "spot", aim: { x, y, z } } — no more yaw/pitch math to rake a spot down onto a pedestal. aim: "down" for ceiling lights, aim: "forward" for headlights and flashlights.
• Anything you set yourself — ambient, hemisphere colors, sun values, or a deliberately pitch-black scene — stays exactly the way you made it.

Ground and walls with real depth. One flag — pbr: true — turns any texture into a real material.

• Terrain blends like actual ground: grass grows up between cobblestones instead of cross-fading, the surface has real relief up close, and materials respond to light correctly (normals, roughness).
• Tell Savi a wall should be brick and it's actually brick: she sets one flag — pbr: true — and on capable desktops it gets depth, self-shadowing between bricks, notched brick silhouettes along its edges, and true displaced geometry up close — with the detail handing off smoothly as you walk away. No extra setup.
• Tiled floors and long paths stop looking like a copy-pasted grid: textures repeated across big surfaces now vary subtly tile to tile, the way real stone and brick do — automatically, with small textures and props keeping their exact authored look.
• Resize a texture pattern the natural way: textureScale: 2 makes cobbles, bricks, or planks twice as large — it composes with the automatic real-world tiling instead of fighting it.
• Everything is tiered for the player's device: phones and weaker laptops keep the simpler look at full speed.

Dig and build with no lag — and it's saved for good.

• Terrain editing is instant now: break a block and it's gone, place one and you're already standing on it. Big builds land at once instead of trickling in block by block.
• Savi got bulk tools too — big builds land as a few commands instead of hundreds: fill a region, carve a moat, stamp a whole watchtower in one go. A wall that used to take 512 separate commands is now 4, so building together keeps pace with the conversation.
• Every edit is saved automatically, in every 5.0 world, with no setting to remember — come back tomorrow and your tunnel is still your tunnel.
• Block worlds finally sit in their lighting: terrain casts shadows now, so a tower throws a long shadow at sunset and a canyon floor falls into shade.

The sky is real now. Every world with a procedural sky gets a physically real one, automatically, the moment it's on 5.0.

• Sunrises, sunsets, twilight, and a sun you can look at. Stay out past dusk and the stars fade in, the milky way arcs overhead, and a moon with real phases rises — and actually lights the world, so a full-moon night is silvery-bright and a new-moon night is properly dark.
• One number scrubs the whole day: set timeOfDay and sun position and color, ambient light, reflections, fog, stars, and the moon all move together with no scripts. 0.8 is a sunset; one cycle line is a day/night loop that runs forever.
• Clouds live in the sky itself now: they drift with the wind, catch sunset colors, glow silver under the moon, and dim the world when it's overcast — the way an overcast day actually feels.
• Want somewhere else entirely? Sun size, horizon tint, milky way brightness, moon size and phase are all dials now — ask Savi for "a Mars sky" or "permanent golden hour" and the atmosphere itself changes, lighting your whole world with it.

Multiplayer, rebuilt — and your game runs the door.

• Multiplayer got a whole new engine: smoother movement, and hits on moving players land where you actually aimed — if your crosshair was on them, the hit counts.
• Rooms hold about 100 players, and when one fills, a fresh room opens automatically and the next player rolls in — your game scales sideways with zero setup.
• Click Play and you're in: joining a world that's already awake lands in about a second, and waking a sleeping one now overlaps with your page load instead of stacking after it.
• Ask Savi for matchmaking and she writes it into your game: keep returning players on their old server, fill the fullest open room before starting a new one, shard by region — a few lines of routing code your game owns and decides which room each player joins. No code at all gets you sensible defaults.
• Rooms have a real player cap: a full room turns players away at the door and routing automatically rolls them into the next room, creating a brand-new one when everything's full. Players just land somewhere playable.
• Ask Savi for a live server browser and she builds it from real data: server lists, matchmaking queues, and per-server saves can now be listed, queried, and locked from in-game scripts.
• Preview: Mantle physics — opt-in per world via physicsEngine: "mantle"; existing games keep their current physics by default.

Enemies have brains. Ask Savi for "an enemy that patrols and chases me when it spots me" — one sentence, and the engine handles everything that used to go wrong.

• Smart movement — enemies walk around obstacles, through doorways, and around each other instead of bumping into walls or piling up. No more zombies stuck on fountains.
• Smooth movement — NPCs walk, break into a sprint, and turn at a natural rate instead of snapping or moonwalking.
• They see and hear — give an NPC vision and it spots you (or loses you when you hide); throw a noise and guards come to investigate. Hide and seek is a real game now.
• Fair fights — enemy groups can take turns attacking instead of mobbing you all at once, and archers keep their distance while staying aimed at you.
• Tune it yourself — select an NPC in god mode and drag its vision ring, pick its speed and hearing, right in the world.

Savi sees your game now — and she's a shader artist.

• Savi can watch your game while you play — through your camera, or an invisible one she flies to check the back of the castle without moving your view. What she reports is her view of the world, and she catches her own mistakes by looking, the way you would.
• Ask for a force field and she writes the actual shader: glowing energy, glass, lava, holograms, dissolves — on anything in your world. Say "slower pulse" or "more green" and it updates live.
• Ask her to preview something and she'll show you a picture before it lands in your world — even a little filmstrip of it animating, or a sweep of variations.
• Whole-screen looks: film grain, retro pixelation, scanlines, color grades, underwater moods. Savi writes the look as a tiny script, tweaks it live, and can fade it in and out during gameplay.
• Every new game now opens with its look already written out as an editable script — the world looks exactly as before, but the dials for color, glow, grain, and vignette are sitting right there. "Warm it up a little" is a one-number edit.
• If a fancy shader ever makes a game run slow, the engine steps in to keep it smooth and tells Savi exactly what to fix — players never get stuck with a laggy world.
• For big asks she fans out a whole team of background builders — splitting the work, gathering it back, sending reviewers over anything that isn't right. You watch the flames in the studio footer while it happens, and if the server blinks mid-build, the team picks up where it left off.

Characters and crowds.

• Characters plant their feet on slopes and uneven ground instead of floating or clipping — and Savi can make them reach, grab, and look: "hand the player the sword" works with no animation files.
• Ask Savi for a marching army or a festival crowd and the engine animates everyone sharing a model in one pass — the clip below runs 360 characters at once, each still walking at its own pace.

Making a mod is exactly as hard as making a folder.

• Put your scripts in a folder with a small mod.json, and that folder is the mod — publishing ships every file in it, including teaching docs for Savi and slash commands for players, so there's no way to forget a piece and ship something broken.
• Every game has a real mod catalog now: browse, search, like, comment, and install in one click — with public, unlisted, and private visibility, so you can soft-launch to friends or keep a mod to yourself.
• Savi knows the catalog: ask her for a shop system and she checks whether another creator already built a great one before building from scratch.
• Installed mods are starting points, not sealed boxes: ask Savi to change how one works and she edits it in place — your edits survive the author's updates, and uninstalling removes exactly what the mod brought.

Building in god mode. Editing by hand got quicker and more physical.

• Spotlights place in two clicks: one for where the light sits, one for what it shines on — the beam follows your cursor between them.
• Right-click anything for its dials: recolor a lantern from a palette, drag its glow radius, set a sound's volume and range, tune an effect's rate and size — all in place, no typing.
• Click a house, get the house: selecting grabs the whole assembly instead of one plank, and clicking again drills down to the tower, the door, the doorknob.
• Every brush erases: hold Alt and brush the extra daisies back out — the ring tints warm so you always know which mode you're in.
• Paint with anything: turn any object — a mushroom, a crystal, a gravestone — into a scatter brush and sweep copies across the hillside.
• Building makes sound now: placing, painting, erasing, and undoing each answer back with their own little sound.
