Tutorial: model a game prop

You’ll model a treasure chest, refine it in a few prompts and export it for a game engine.

First, connect 3D-Agent to Blender.

1. Start with a clean scene

   In Blender, open a new file and save it as treasure-chest.blend. A saved file gives your checkpoints a name.

2. Describe the prop

   Say what it is, its style, its size and what it’s for:

   Model a wooden treasure chest with iron bands and a lock, stylized for a mobile game. About 1 m wide, sitting on the ground at the origin. Keep it under 5,000 triangles.

   3D-Agent builds the chest and checks its own work.

3. Refine it

   Change one thing per prompt, so each change gets its own checkpoint:

   • Make the lid slightly open and add gold coins inside.
   • Round the corners of the iron bands.
   • Give the wood a warm, worn look.

   If a change goes wrong, open Checkpoints and restore the version before it.

4. Get it ready for the engine

   Apply all modifiers and scale, set the origin to the bottom center, and name the object TreasureChest.

5. Export

   In Blender, open File → Export. Pick FBX (.fbx) for Unity or Unreal, or glTF 2.0 (.glb/.gltf) for Godot. See Exporting.
