Build everything.
Then go beyond.

A powerful, flexible, open-source game engine.
From your first idea to a world of your own.

01 / Meet Atlas

Engine, without
the ceremony.

Atlas combines a visual editor, modern rendering and a modular C++ runtime. Start with a scene. Shape every detail. Go as deep as your idea demands.

Atlas scene editor with a scene hierarchy, 3D viewport, inspector and content browser — The Atlas editorYour scene. Everything in reach.

One connected workflow.

Build your scene, organize assets and adjust objects in a workspace that keeps your project in view.

Room to experiment.

Explore materials and lighting, then switch from a real-time preview to a path-traced view.

Control down to the core.

Work visually or dive into C++. Open source means you can understand, extend and make the engine yours.

02 / Look closer

Bring your ideas
into the light.

From the first material to the final atmosphere, explore how light changes a scene. Preview as you work, then let the details emerge with path tracing.

Light & rendering

A new way to see your scene.

Explore reflections, shadows and indirect light with the integrated path-traced view.

Materials & shading

Make every surface your own.

Refine the materials that give objects their character, all within the editor.

03 / Under the hood

Small pieces.
Big possibilities.

A family of focused systems, connected by a common foundation. Use Atlas as a complete engine, or explore the pieces that power it.

Explore the architecture

01 / The foundation

Atlas

Scenes, resources, input and a runtime that brings everything together.

02 / The renderer

Opal

A graphics abstraction connecting Metal, Vulkan and OpenGL.

03 / The world

Aurora

Terrain and outdoor systems for worlds with room to explore.

04 / The physics

Bezel

Movement, collisions and simulation that give your world substance.

05 / The sound

Finewave

Spatial audio, playback and real-time sound processing.

06 / The light

Photon

Path-traced rendering for a different perspective on your scene.

07 / The Atmosphere

Hydra

Weather, sky and clouds that respond to your scene and the sun.

08 / The UI

Graphite

A flexible system for building in-game interfaces and editor tools.

09 / The profiler

Tracer

A real-time view of performance, memory and GPU usage.

Open source. Open possibilities.
