// how it works

How it works

  1. Pick build or generate

    Game engines and modelers for handcraft; AI tools for text-to-3D assets.

  2. Install the toolchain

    Mature installers and package managers on every platform.

  3. Learn the workflow

    Nodes, scripts, or prompts — each tool has strong community tutorials.

  4. Export anywhere

    Standard formats (glTF, FBX, OBJ) move assets between tools.

// features

Why people love it

Real 3D

True three-dimensional pipelines, not flat approximations.

Real-time rendering

Modern pipelines with PBR, GI, and post-processing.

AI asset generation

Text-to-3D and image-to-3D for rapid prototyping.

No royalties

Ship commercial games without revenue share.

Full source access

Modify the engine itself — impossible with closed tools.

VR/AR ready

Several engines support immersive targets out of the box.

// run it

Run it yourself

  1. Step 1 — Clone the repo

    Download the source and move into the project folder.

    git clone https://github.com/Roblox/cube.git
    cd cube
  2. Step 2 — Check the README

    Every project documents its own setup; start with install requirements.

    cat README.md | head -60
  3. Step 3 — Run it

    Follow the project's launch command — Docker, pip, npm, or a binary release.

    # see README for the exact launch command
// use cases

Questions, answered

Who maintains cube?

It is an open-source project at Roblox/cube with 139 forks. Check the repo's contributors and recent commits to see how active maintenance is.

Is cube free for commercial use?

Licensed under Unknown — check the repo for commercial-use terms.

Do I need to code?

Visual scripting covers a lot; GDScript/Python is easy to pick up.

Can it compete with Unity/Unreal?

Godot has shipped commercial hits; for AAA-scale productions the big two still lead.

What formats work?

glTF is the lingua franca; FBX/OBJ import is universal.
