// 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.

Huge asset commons

Community models, materials, and add-ons, free.

Cross-platform export

Ship to desktop, mobile, web, and console targets.
