A good look by default
A scene that sets no exposure gets automatic exposure in the high-definition renderer, and both renderers share the same default tone curve, so a first scene looks right in either.
Roadmap
What has shipped, what is coming in the next release, and what is planned. Later items are directions, not promises.
Shipped in v0.7.0
In the newest release.
Rendering and lighting
World building
Paint forests with a brush
Paint or erase plants with a brush, and draw thousands as one instanced object, each with a stable identity. Tested headless with a million instances: scene load, memory and physics.
Animation and characters
Layered animation with hit windows
Layer animations by body part (swing a sword while running), mark cancel and hit windows on the clip timeline, and attach weapons and sensors to bones so hits register where the blade actually goes. Feet plant on slopes.
Bring your own animations
Convert FBX, BVH, glTF and Blender clips onto one standard humanoid skeleton and play any clip on any character. A contact-sheet preview shows the result before you import.
See your animation graph at work
The editor shows a character's animation graph: its states, transitions, layers and parameters, with the current state lit while the game plays. Press a state to preview its clip, or scrub any clip in the scene view.
Audio
Music for your game
Generate background music through a connected music service using your own account, or import tracks you already have. Where each track came from is recorded with it.
Editor and workflow
Prefabs inside prefabs
Build a prefab from other prefabs: a house from walls and windows, a street from houses. A change to an inner prefab reaches every place that uses it, and a loop or runaway nesting is caught with a clear message.
Shipped in v0.6.0
Released earlier.
Rendering and lighting
Write shaders with guard rails
A shader code panel with colors, sliders generated from the code, error hints, a cost meter and a live preview. One shader file works in both the standard and high-definition renderers. Desktop exports prepare every shader while loading, so play does not stutter the first time an effect appears.
Facet: detail without triangle budgets
Meshes with millions of triangles draw only the detail the screen can show, so you stop hand-making lower-detail versions. Rocks, trunks and scanned props stay sharp up close and cheap far away. Geometry streams from disk as the camera moves. Available in the high-definition renderer.
Far-away worlds that stay cheap
Distant trees turn into baked billboards automatically, so long view distances stay affordable. Available in the high-definition renderer.
Solstice: real-time light and reflections
Light bounces around the scene live: sun, sky and glowing surfaces light everything they face, and reflections include objects that are off screen. It needs a graphics card with ray tracing; without one, the scene uses simpler lighting and the engine reports why. Available in the high-definition renderer.
Sharp, stable shadows
In the high-definition renderer, sun shadows are cached and only redrawn where something moved, so wide views stay sharp and cheap, and point and spot lights cast shadows too. On graphics cards with ray tracing it can trace shadows, and swaying trees and animated characters show up in them as they move.
Physical sky and clouds
A sun-driven sky with volumetric clouds, cloud shadows and distance haze. Available in the high-definition renderer. Optional automatic exposure, where the camera adapts like an eye between shade and sunlight, arrives in the next release.
Physically based materials
Metal, clear-coat car paint with flakes, back-lit leaves and cloth, and correct overlapping transparency in the high-definition renderer. Upscaling and multisampling keep edges clean.
World building
Oceans with weather
A sea that goes from calm swell to a gale, with foam, spray off breaking crests at the Ultra preset, calm harbors you paint with a mask, and waves running up a shore you describe with a height map. Floating objects ride the real waves, and replays on the same machine give the same result. Available in the high-definition renderer.
Terrain from a recipe
Describe a landscape as a stack of steps (shape, noise, erosion that carves real valleys, flattened pads, shorelines) and the engine builds the same terrain every time. Collision comes with it, and navigation can be baked from it. Materials that put rock on cliffs and snow up high arrive in the next release.
Rivers and lakes that follow the land
Rivers and lakes form from the terrain's own drainage, and floating objects are carried downstream. Several fresh-water looks are built in. Drawn in the high-definition renderer.
Plants, grass and scattered forests
Grow trees and shrubs from recipes and scatter them over the terrain. Grass and wildflowers move in the wind.
Navigation meshes that follow the terrain
Characters find paths over built terrain and scenes, including paths that need a jump between ledges. The navigation mesh is baked from the same data as collision.
Animation and characters
Animation blending and events
Blend between animations, fire events from points on a clip, and let root motion move the character. Feet are placed on the ground with inverse kinematics.
Physics and vehicles
Cars, karts and boats that handle
Suspension wheels with grip that depends on the surface under each tire, ready-made presets including a drifting kart, and roads built from a file. Boats and other floating craft move on the real ocean waves.
Physics you can replay
Rigid bodies, joints, triggers and collision layers on a fixed time step. Run a scene with the same inputs on Windows or Linux and you get the same result, checked every night, so replays and automated tests can rely on it.
Gameplay and scripting
Scripting in TypeScript
Write gameplay in TypeScript, with type checking and changes picked up while the game runs.
Record a session, replay it later
Save a play session's input in a small file and replay it later at any size and from another camera, for reviews and trailers. A profiler capture can replay the same run against your edited project to check a fix.
Effects
Particle effects
Emitters with eight ready-made presets such as fire, smoke, sparks and dust. At the Ultra preset, rough seas throw spray, and waterfalls make mist.
Audio
Mixer, positional sound and generated effects
Buses with effects, sound that comes from where things are, and engine sounds that follow speed. Simple sound effects (blips, whooshes, engine loops) can be synthesized from presets or a few settings, no recordings needed.
UI, 2D and input
Game menus you and an AI can both edit
Build screens in a familiar web-like style with layout, styles, focus and gamepad navigation. Show 3D models inside menus. Games can be played by touch.
2D games
Sprites, sprite sheets and tile maps work with the same physics, menus and tools as 3D. A 2D platformer sample comes with the next release.
Input for every device
Keyboard, mouse, gamepad and touch through one set of named actions that players can remap. A control map can turn regions of a touch screen into sticks, look drags, buttons and taps.
Editor and workflow
Edit while the game runs
Change a script, a scene or a shader and see the result without restarting the game. Most of the game keeps running; only an edited script is re-initialized, and it keeps its saved state.
Find out why your game is slow
A profiler tab shows every frame against your budget; click a spike to see its timeline and flame graph. Your AI assistant can ask for a ranked list of likely causes with estimated savings. Recording is on while you develop and costs a few microseconds a frame, so the slow moment is already captured.
Play, slow down, step outside the game
Run the game inside the editor, slow it down or speed it up, and step out into a free camera to inspect or move things while it keeps running. Simulate runs the game with no player input.
Cinematic cameras without scripting
Holds, paths, orbits and follow shots with cuts and smooth blends, set up in the scene, no code needed.
Watch your game being built
Presentation view turns the editor into a clean show: the scene slowly orbits while a live feed shows what your AI assistant is doing. Made for streams and demos.
The editor essentials
Content browser, prefabs, project settings and built-in bug reports. Almost every editor action also has a tool, so an AI assistant can do the same work in its own editor.
AI assistants
Built for AI assistants
An AI assistant can create projects, write scenes and scripts, play and capture the game, test it and profile it, and is told why whenever an action is refused. From the next release, the launcher connects a supported assistant to a project in one step.
Automated playtesting
A built-in playtester runs your game without a window, drives the player toward the scene's goals and reports dead controls, soft locks, script errors and silent audio. A check before play catches broken references.
Platforms and shipping
Bring your models
Import glTF models with their materials. Textures are compressed for each platform when you export.
Export to Windows, Linux and the web
Export a single .exe that runs on a Windows 10 or 11 PC (64-bit) with nothing installed, or a Linux build with a tarball or an AppImage. Web export, a static folder for browsers with WebGPU, is in preview.
Engine versions and projects in one place
Install, check, update and remove engine versions side by side, start from a sample, and keep every project on the version it was made with. A step-by-step start page that takes you from install to a game you can send someone arrives in the next release.
Next release: v0.8.0
Done or being finished for the next release.
Rendering and lighting
Sharper terrain and distant forests
More terrain detail, better distant forests, and the standard and high-definition renderers looking alike.
Local exposure
Bright skies and dark interiors both readable in the same view.
Volumetric light and better skin
Light shafts through fog and haze, scenes with many lights, and better translucency and skin.
World building
Terrain from a description
Generate whole terrains from a few words, starting from real height data.
Generated towns and buildings
Generate buildings and small settlements from a recipe, ready to walk through.
Huge streaming worlds
Large maps load in pieces around the player, and pathfinding keeps working across them.
Effects
Squall: a new effects and fluids system
Squall will add fluid simulation and more ready-made effects, authored as data that you and an AI can both edit.
UI, 2D and input
Better 2D
2D lighting and a pixel-perfect camera.
Editor and workflow
A faster first hour
Clearer start-up steps, plain error messages and more samples.
AI assistants
Generate or reuse assets
Search a shared library first, and generate concept art or 3D models only when nothing fits, with the price shown before every paid step. Each generated model is checked for game-readiness, and where it came from is recorded with it.
Several assistants at once
More than one AI assistant building your game while you play-test it.
Multiplayer
Couch co-op
Split-screen play for up to four players with gamepads.
Platforms and shipping
Windows, Linux and web in every release
Closing the gaps so Windows, Linux and web builds get the same features and tests.
Phones and Mac
Android and iPhone builds, and Mac.
Later
On the list with no release yet. Directions, not promises.
Rendering and lighting
Hair and fur
Individual hair strands and fur.
World building
More ways to move
Navigation for swimming, flying and driving.
Precision far from the origin
Positions that stay precise far from the center of the world, for very large maps.
Animation and characters
More character tools
Facial animation and ragdolls.
Motion matching
Natural movement picked from a library of motion.
Physics and vehicles
Cloth and soft bodies
Flags, capes and squishy objects that react to the world.
Destruction
Pre-fractured objects that break on impact, replayable like the rest of the physics.
Gameplay and scripting
Thinking characters at crowd scale
Thousands of non-player characters that see, hear and decide every moment, written as short rule lists in TypeScript, giving the same results for the same inputs whatever the thread count.
Dialogue and quests
Ready-made building blocks for dialogue and quests.
Audio
Spatial audio
Sound blocked by walls and shaped by the room it is in.
Adaptive music
Music that changes with the action, moving between layers and sections as the game state changes.
Editor and workflow
Team collaboration
Version control and merging of scenes from inside the editor.
Cinematic timeline
Cut-scenes on a timeline with cameras, animation and sound in sync.
Plugins
Extend the editor and the engine with your own tools.
Community asset library
Share and find assets made by other developers.
Multiplayer
Online multiplayer
Online multiplayer, built on the engine's fixed-step simulation and replays. The groundwork is in the engine for the next release: our test scenes run to identical results on Intel and AMD processors and on Windows and Linux, the engine can rewind and re-run its last frames, which online play will use to correct for network delay, and a world can be rebuilt exactly from one snapshot, which is how a late joiner will catch up. The networking itself comes next.
Dedicated servers
Dedicated servers for online games.
Matchmaking and leaderboards
Accounts, matchmaking and leaderboards for online games.
Voice chat
Voice chat for online games.
Platforms and shipping
Headsets
From the next release, you can build and test for virtual reality without a headset: a desktop stand-in for the headset with a virtual head and hands, profiles for common headsets, scripts that read them, and UI panels placed in the world. Real headsets come later.
A quality level for phones
Rendering settings tuned for phones and other low-power devices.
Cloud builds
Build and test your game in the cloud on every change.
Crash reports
Crash reports from your players, with the details needed to fix them.
