name: blockbench-create-model description: Create a complete, fully-textured 3D model in Blockbench through an interactive interview process.

Create 3D Model (Geometry Only)

Build a 3D model's geometry in Blockbench. This skill creates the shape - use blockbench-texture afterward to add materials.

Overview

1. Interview the user about the model
2. Create the project (Hytale Prop format)
3. Build geometry (cubes and groups)
4. Verify with screenshots
5. Hand off to texture skill

Phase 1: Interview

Use AskUserQuestion to gather:

Required Information

Component Naming Convention

Name components by their intended material for easy texturing later:

---

Phase 2: Create Project

Copymcp__blockbench__create_project({
  name: "model_name",
  format: "hytale_prop"
})

Important: Close any other open projects first (single project rule).

---

Phase 3: Build Geometry

3.1 Create Root Group

Copymcp__blockbench__add_group({
  name: "root",
  origin: [0, 0, 0],
  rotation: [0, 0, 0]
})

3.2 Build Order

1. Base/frame - Bottom structural elements
2. Main body - Largest central volumes
3. Secondary shapes - Attached components
4. Detail pieces - Small trim, accents, controls

3.3 Place Cubes

Copymcp__blockbench__place_cube({
  elements: [
    { name: "base_plate", from: [-8, 0, -8], to: [8, 2, 8] },
    { name: "body_main", from: [-6, 2, -6], to: [6, 12, 6] }
  ],
  group: "root"
})

Geometry Guidelines

3.4 Add Detail

For medium/detailed models, add:

• Corner posts - Small vertical cubes at corners
• Trim pieces - Thin horizontal cubes at edges
• Vents/grills - Repeating thin cubes
• Control panels - Recessed or protruding sections
• Pipes/tubes - Cylindrical arrangements of cubes

---

Phase 4: Verify Geometry

Take Screenshots

Copymcp__blockbench__set_camera_angle({
  position: [30, 20, 30],
  target: [0, 8, 0],
  projection: "perspective"
})

mcp__blockbench__capture_screenshot()

Check from Multiple Angles

• Front: position: [0, 10, 30]
• Side: position: [30, 10, 0]
• Top: position: [0, 40, 0]

Verify Element List

Copymcp__blockbench__list_outline()

Confirm all components are created with correct names.

---

Phase 5: Hand Off to Texturing

After geometry is complete, inform the user:

"Model geometry is complete with X elements. Use /blockbench-texture to create and apply materials."

Provide a summary of element names grouped by intended material:

• Dark iron: base_plate, frame_front, trim_bottom...
• Steel: body_main, panel_left, vent_1...
• Copper: dial_1, switch_2, pipe_inlet...

---

DO NOT

• Create textures (that's the texture skill's job)
• Apply materials or set UVs
• Use the texture parameter in place_cube
