// 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.
