Everything you need to ship
Rendering, physics, scripting, animation, and AI - a complete engine designed so you can focus on making your game, not fighting your tools.
Forward+ Rendering
Thousands of lights. Zero compromise.
PBR materials with Image-Based Lighting, Forward+ tiled light culling, and a full post-processing stack - SSAO, bloom, depth of field, motion blur, color grading, and FXAA. What you see in the editor is what ships in the game.

Materials
Material Forge
Node-based. Real-time preview. No shader code.
Build materials visually by connecting nodes - textures, math, procedural noise, and PBR outputs. The viewport updates in under 50ms. Create anything from realistic metals to animated lava without writing a single line of WGSL.

Physics & Simulation
Rigid bodies. Ragdolls. Vehicles. Fluids.
A complete physics engine powered by Rapier with rigid body dynamics, soft bodies, ragdolls, vehicle simulation, character controllers, and GPU-accelerated fluid simulation using FLIP/SPH. Drop objects in, add colliders, hit play.

AI-Native Architecture
AI built into the engine. Not bolted on.
The built-in Sense assistant helps you generate assets, debug scripts, and prototype ideas using LLM-driven development. Python bindings connect directly to ML pipelines for training and inference. MCP integration enables AI-driven scene manipulation.

Animation & Combat
Skeletal animation. State machines. Blend trees.
Import rigged characters from glTF and FBX. Build animation state machines with blending, root motion, and ragdoll transitions. Runtime bone attachment and event-driven projectile systems for combat - everything needed to ship a character-action game.

Lua Hot-Reload Scripting
Write gameplay in Lua with instant feedback - save and see changes without restarting the editor.
Visual Scripting
Flow Editor with node-based visual scripting for designers who prefer not to write code.
In-Editor Play Mode
Play, pause, and stop scenes in the editor. Your scene state restores automatically when you stop.
Real-Time Profiler
CPU, GPU, and memory profiling with recording, log capture, and CSV/JSON export.
Asset Pipeline
PAK packaging with zstd compression and AES-256 encryption. Background streaming with priority system.
Custom ECS
Archetype-based Entity Component System built in Rust. 8x faster than OOP for 100K entity updates.
Atmospheric Rendering
Day-night cycle, volumetric clouds, fog, and dynamic sky simulation out of the box.
Multiplayer Networking
Server-authoritative networking with dedicated server builds. No rendering overhead on the server.
Modular architecture.
Built to scale.
Dreams Engine is structured as a layered system of independent modules. Each subsystem has a clear responsibility and a well-defined interface - use only what your project needs.
The full editor, standalone game player, and live preview - everything you need to build your game and ship it to players.
Rendering, physics, scripting, and simulation - purpose-built systems that work together seamlessly so you don't have to glue things together.
The foundation that powers everything above - entity management, GPU resources, asset packaging, and multi-threaded task scheduling.
Script anything with Lua
Write gameplay logic in hot-reloadable Lua with a clean, consistent API. See your changes instantly without restarting the editor.

Performance is not an afterthought
Built from the ground up in Rust for speed and reliability. Your editor stays responsive, your frames stay smooth, and your builds stay small - so you can focus on making your game great.
Smooth, Predictable Frames
Built in Rust with no garbage collector - your game runs at consistent frame rates without random stutters or pauses.
Fast Iteration
Script changes apply instantly. No waiting for long compiles or editor restarts. Write, save, play - in seconds, not minutes.
Scales With Your Scene
Thousands of objects, complex lighting, dense environments - the engine handles it without slowing down your editor or your game.
Memory Safe
Entire categories of crashes - null pointers, memory leaks, data races - are eliminated before your game ever runs. Fewer bugs, more shipping.
More from the devlog
Earlier builds and experiments, straight from the editor.
Documentation
Comprehensive guides covering every subsystem - from your first scene to shipping your game.
