Modeling 3D with Blender MCP

When the user says something like "I need a 3D model of a [Brand] [Model] SUV" or "generate a 3D model of [newly released product]":

1. Research the subject online (specs, dimensions, reference images, silhouette, proportions).
2. Write a Model Brief (dimensions, key design features, reference image links, phase plan).
3. Execute the build in Blender via MCP, phase by phase, checking geometry after each phase.
4. Deliver: .blend file + render preview + brief summary of what was modeled.

Python
# Example MCP call pattern (pseudo, adapt to actual blender-mcp tool signature)
blender_mcp.execute(code="""
import bpy
bpy.ops.mesh.primitive_cube_add(size=2)
obj = bpy.context.active_object
obj.name = "SUV_Body_Blockout"
obj.scale = (2.3, 4.6, 1.75)  # width, length, height in meters from research brief
""")

Never start modeling without a brief. Research first, model second.

Phase 0 — Brief Gathering (always first)

• If user gives a brand + model (e.g., "Toyota Land Cruiser 2024" or "Tesla Cybertruck"): web-search for:
  • Official dimensions (length, width, height, wheelbase, ground clearance)
  • Reference images (front, side, rear, 3/4 view)
  • Distinct design language (grille shape, headlight style, body lines, proportions)
• If user gives a generic request ("a SUV", "an industrial pump"): search for category-defining references and propose a design direction, confirm briefly with assumptions stated (don't block on approval — proceed with reasonable defaults, state them).
• Summarize findings into a Model Brief:
  • Real-world dimensions (convert to meters for Blender units)
  • Key surfaces/features list
  • Reference image URLs
  • Phase plan (see below)

Phase Plan (standard for vehicles/industrial objects)

Progress:
- [ ] Phase 1: Blockout — primitive proxies at correct real-world scale/proportions
- [ ] Phase 2: Base Mesh — main body form via box modeling / mesh extrusion, correct silhouette from all views
- [ ] Phase 3: Detailing — panel lines, greenhouse, wheel arches, grille, lights, mirrors, handles
- [ ] Phase 4: Hard-surface refinement — bevels, edge creasing, subsurf-ready topology
- [ ] Phase 5: Wheels/undercarriage/mechanical subsystems (if applicable)
- [ ] Phase 6: UV unwrap + material/PBR shader setup
- [ ] Phase 7: Lighting + render pass for preview
- [ ] Phase 8: Export/cleanup (apply modifiers, check scale, naming, collections)

Execution rules per phase

• Send one focused MCP script per phase — don't cram all geometry in one call.
• After each phase, take a viewport screenshot / render via MCP and visually sanity-check proportions against reference.
• Name every object/collection meaningfully (Body_Shell, Wheel_FL, Grille, Headlight_L) — never leave default Cube.001 names.
• Keep real-world scale (meters) throughout; never model arbitrary unitless blockouts.
• Use modifiers (Mirror, Bevel, Subdivision Surface, Solidify) instead of manual symmetric duplication.

Brand/Model-Specific Requests

• Always research the specific trim/year if given.
• If exact model can't be found (too new/no data), state the assumption ("no public specs yet, using closest predecessor + general segment proportions") and proceed — never stall.
• Respect trademark/IP sensitivity: model in the style of, don't claim official licensed assets.
