Engine v5.1.11

July 6, 2026

A patch to Connection.

Savi can now invent animations for your characters — a swim stroke, a dance, a wing-flap — by writing them as motion code, no animation files needed. They play (and blend) just like regular animations, and edits take effect at the next loop so nothing pops mid-motion.
Savi can now watch your game in motion, not just look at frozen screenshots — she grabs a short filmstrip of live frames, so she can actually judge whether the walk cycle slides, the jump feels floaty, or the boss swing lands on beat.
Game managers can now be read from anywhere! Add replicate: "world" to a manager object (like your game's phase or score tracker) and every player can see its state no matter which area they're in — no more copying state onto each player to work around it.
Scripted splines work again: paths that sweep a custom cross-section you describe in a script (walls, tubes, ribbons — any shape) now save properly instead of being rejected. Scripts can also scatter objects along the path — lamp posts down a walkway, pillars under a bridge — and they'll appear right where the path runs.
Effects no longer silently switch to a lower-quality renderer under load — the engine fits many more effects at once (128 default-sized effects on desktop, up from ~12–16), and anything truly beyond budget waits its turn instead of changing how it looks. When an effect does have to wait or shrink, the engine now says so instead of staying silent.
Fixed a bug where a big world could get stuck blinking — the whole scene vanishing and popping back every few seconds, forever. If a piece of scenery ever fails to reach a player now, the world stays put and the engine reports the problem instead of strobing (that one piece may need a reload to appear).
Fixed a leak that could slowly fill up your graphics card during long sessions in big worlds — especially ones that rebuild the scene a lot. No more "my GPU crashed" after a long build session.
Animated characters no longer show up pitch black in softly-lit scenes. If your character model looked fine near a lamp but turned into a silhouette everywhere else, that's fixed.
Feet touch the ground: sprites with empty space baked below the art (most generated side-view creatures and props) used to float above the floor — now they stand exactly on it, and their colliders line up with what you see.
Your ambient light now does what you asked: worlds that set the ambient color and brightness in the common flat form used to silently render a dim gray instead. Existing dark 2D worlds get the brightness their creator originally wrote as soon as they update to this engine version.
Cameras tuned with a small smoothing value (like 0.15) now follow the way you meant — snappy, not floating seconds behind the player. The engine recognizes the common "fraction per frame" style and applies the matching follow speed.
Generated shapes now render both sides — backwards-facing surfaces stop going invisible. When Savi writes procedural geometry (roofs, furniture, terrain details), a face wound the "wrong" way used to vanish when viewed from the intended side; now it just renders.
Name tags sit where they belong on resized characters: giants no longer wear their names inside their heads, and tiny characters no longer have names hovering way above them.
Rigs and builds made of many custom-geometry panels that share one material script (like skeletal character rigs) no longer freeze the game for seconds on first spawn — all panels now share one compiled material, each still rendering its own colors and atlas regions.
Scripts that return odd values no longer lose their changes: if Savi's script ended by returning something that couldn't travel back in the reply (a live logs handle, a function), the engine used to throw away everything the script had built — "my changes keep disappearing." Now the changes land and only the return value is replaced with a note explaining what to return instead.
Savi's script changes stop vanishing over reply problems, part two: a script that successfully changed your game but returned a value the reply couldn't carry (a circular structure, a BigInt) used to have the whole answer thrown away — Savi was told her changes failed, rebuilt the same thing by hand, and the saved game never got the changes. Now the changes always land and save; only the unreportable return value is replaced with a note telling Savi what happened.
Editing scripts while your game is running is much more reliable now: event handlers always pick up your latest code — no more "my fix doesn't work until I restart the room", and no more handlers firing twice (or four times) after repeated edits.
Live script edits can no longer leave an object secretly deaf to events: if an edit orphans an object's old event handlers, the object now tells you loudly — naming the event and the script, with the fix (re-save the script; if it stays deaf, restart rooms) — instead of your correct fix looking like a no-op.
When a script accidentally uses the wrong import/export style, the error now explains exactly what to change instead of a cryptic one-liner — so Savi fixes it on the first try instead of guessing.
World thumbnails and Savi's screenshots recover cleanly when the graphics engine stalls, instead of silently hanging forever.
Your world's shelf image refreshes while you build — the picture on your worlds list updates every few minutes during a live session instead of freezing at the first screenshot.
Savi learned from this week's play sessions: she now fully deletes things you ask her to remove (no invisible leftovers), makes "hesitant" NPCs pause to think instead of moving in slow motion, wires up saving correctly for spawned objects, and has worked examples on tap for combat waves, enemy AI, and damage zones.
Enemies and props whose 3D models are still generating no longer get reported as permanently broken: the engine used to log hard "extraction error" failures while a model was simply mid-cook (so Savi and dashboards read your placeholder pills as abandoned), and now it correctly treats "still generating" as waiting — it keeps checking on schedule and the real model swaps in the moment generation finishes.
Fixed a chronic multiplayer glitch family: after a reconnect or a shaky connection, players' body parts and other respawning objects could silently stop syncing to everyone else (the server kept rejecting them as "already exists"). They now heal in place automatically.
Building in god mode no longer leaks editor gizmos into the shared world — friends will stop seeing stray rings and handles hovering around objects you were editing.
Fixed the worst "my game is frozen for one player" bug: on a slow or congested connection, a player's world could stop updating forever — joins that never load, props that never spawn, refreshes that don't help — while everything looked connected. It now recovers within seconds, so the worst case is a brief hiccup instead of a permanently frozen world.
Sky clouds are back: worlds using the realistic sky's built-in cloud layer have been rendering an empty sky since engine 5.1.9 — the settings were right and saved all along; the engine was quietly throwing away the clouds' first paint while their shader warmed up, then never repainting. It now retries until the paint actually lands, so your clouds show up seconds into the session, every session. Night skies get the same fix for the milky way.
