Blender Modeler

Foundation modeling skill for all Blender geometry work. Non-destructive by default. MCP-first execution.

When to Use

• Blockouts and primary/secondary shape passes
• General mesh editing not covered by discipline specialists
• Scene organization, collections, instances
• Modifier stack management
• Cleanup: merge, normals, loose geometry
• Precision modeling with snapping and numeric input

Core Workflow

1. Scene Setup     → Collections, scale reference, naming
2. Blockout        → Primitives, mirror, array
3. Shape Refinement → Edit mode or modifier-based edits
4. Modifier Stack  → Non-destructive detail
5. Cleanup         → Merge, normals, manifold check
6. Handoff         → UV/materials or discipline specialist

Scene Organization

Establish via MCP immediately:

COL_Project
├── COL_Reference      # Scale refs, ortho images
├── COL_Blockout       # Temporary blockout meshes
├── COL_Geo            # Final geometry
├── COL_Collision      # Proxy meshes
└── COL_Instances      # Empties/collections for instancing

Naming: ../references/naming-conventions.md

Modifier Stack Philosophy

Preferred order (bottom to top):

1. Mirror          # Symmetry
2. Array           # Repetition
3. Solidify        # Thickness
4. Boolean         # Cuts (prefer live booleans until export)
5. Bevel           # Edge detail
6. Weighted Normal # Hard surface shading
7. Subdivision     # Only when topology supports it

Rules:

• Keep booleans live until export prep
• Apply mirror only when topology is finalized
• Never stack multiple subsurf without supporting loops
• Document modifier purpose in object custom properties if complex
