# Vehicle Artist

Proportion-driven vehicles. Clear body language. Manufacturing panel flow. Engine-ready LODs.

## When to Use

- Cars, trucks, bikes, aircraft, boats, ships
- Mechs and large mechanical walkers
- Transit / industrial vehicles
- When vehicle work should not live under generic hard-surface

## Design Principles

1. **Proportion blockout first** — Wheelbase, cabin, mass distribution
2. **Centerline symmetry** — Mirror early; break only for damage/wear
3. **Panel flow** — Seams follow stamped/assembled construction
4. **Functional readability** — Lights, intakes, doors, wheels read clearly
5. **Separate systems** — Body, wheels, glass, interior, lights as objects

## Workflow

```
Ortho refs → Chassis blockout → Body volumes → Wheel/suspension
  → Panel breaks → Booleans/cutters → Bevels → Glass/lights
  → Interior (LOD-aware) → UVs → Materials → LODs → Collision → Export
```

## Blockout Checklist

- [ ] Overall length / width / height locked
- [ ] Wheel size and stance correct
- [ ] Cabin / canopy silhouette readable
- [ ] Ground clearance intentional
- [ ] Symmetry axis established

## Object Split (Game)

| Object | Why |
|--------|-----|
| `SM_Vehicle_Body` | Main shell |
| `SM_Vehicle_Wheel_*` | Spin / steer |
| `SM_Vehicle_Glass` | Transparency / sorting |
| `SM_Vehicle_Light_*` | Emissive materials |
| `SM_Vehicle_Interior` | Cull on distant LODs |

## LOD Guidance

| LOD | Focus |
|-----|-------|
| LOD0 | Full panels, interior if visible |
| LOD1 | Simplified panels, remove micro |
| LOD2 | Body + wheels + glass only |
| LOD3 | Impostor / ultra-low hull |

Use `lod-pipeline` for generation and validation.

## Collision

- Simple convex hulls per major volume
- Wheel capsules/cylinders separate if physics-driven
- See `collision-proxy`

## Constraints

### MUST DO
- Lock proportions before panel detail
- Keep wheels as separate objects when animated
- Plan LODs and collision with body

### MUST NOT DO
- Detail interior before exterior silhouette
- Boolean chaos without cutter collection
- Single merged mesh for all systems on game vehicles
