I'm developing an OSRS-style MMORPG with Indian mythology theme
and need a custom modular character system.

**Project**: Legends of Hastinapur (Bevy engine)
**Scope**: 1 base character + 5 animations + 3 armor pieces
**Style**: Low-poly (2-3k tris), culturally authentic
**Format**: GLTF/GLB + Blender source files
**Budget**: $[YOUR BUDGET]
**Timeline**: 3-4 weeks preferred

I've attached:
- Full commission brief
- Mood board with references
- Technical specifications

Could you provide:
1. Availability and start date
2. Your project quote (or confirm budget fits)
3. Estimated timeline
4. 1-2 small test sketches (small fee paid)

Portfolio piece I liked: [LINK TO THEIR WORK]

Looking forward to working together!

Best,
[Your Name]

• Ask for test

• Negotiate milestone payments (never 100% upfront)
• Clarify revision policy (2-3 rounds standard)
• Get everything in writing

Week 2-3: Commission in Progress (5 hours/week monitoring)

Your Tasks While Artist Works:

1. Set Up Asset Pipeline (8 hours):

   # Create asset directory structure
   mkdir -p ~/Documents/loh/loh-game/assets/models/{characters,props,armors}
   mkdir -p ~/Documents/loh/loh-game/assets/references
   
   # Test GLB import in Bevy
   # Create test scene with placeholder cube
   # Verify asset loading works

2. Weekly Check-ins:
   • Monday: Request progress update
   • Review WIP screenshots
   • Provide feedback within 48h
   • Track milestone completion
3. Prepare Integration Code (6 hours):

   // Start writing character customization system
   // See: /agent-docs/custom_3d_assets_indian_mythology.md
   // Section: "Character Customization System (Code)"

Week 4: First Delivery & Revisions (10 hours)

When Assets Arrive:

1. Validate Deliverables (2 hours):
   • All files present (GLB + Blender source)
   • GLB imports without errors
   • Animations play correctly
   • Poly count within spec (check in Blender)
   • Textures display properly
2. Test in Bevy (3 hours):

   fn test_character_load(
     mut commands: Commands,
     asset_server: Res<AssetServer>,
   ) {
     let character = asset_server.load("models/characters/warrior_base.glb#Scene0");
     commands.spawn(SceneBundle {
         scene: character,
         transform: Transform::from_xyz(0.0, 0.0, 0.0),
         ..default()
     });
   }

3. Request Revisions if Needed (5 hours):
   • Make annotated screenshots
   • Be specific: "Left arm pinches during walk animation at frames 12-15"
   • Prioritize critical issues vs nice-to-haves
   • Usually get 2-3 revision rounds

Week 5-6: AI-Generate Armor Variations (15 hours)

Now that you have base character, create variations:

1. Set Up Meshy.ai (1 hour):

2. Generate Armor Pieces (10 hours):

   Session 1 (2h): Helmets
   - Prompt: "low poly bronze helmet, Indian warrior, ornate, game asset"
   - Generate 5 variations
   - Download best 3 as GLB
   
   Session 2 (2h): Chest Armor
   - Prompt: "low poly scale mail, ancient India, bronze, game prop"
   - Generate 5 variations
   - Pick best 3

Week 7: Assembly & Integration (20 hours)

Create Character Variants:

1. Manual Assembly (8 hours):
   • Open Blender
   • Import base character
   • Import armor piece
   • Parent armor to correct bone
   • Export combined GLB
   • Repeat for 10-15 combinations
2. OR Automated Assembly (12 hours to set up, then instant):

   # I'll provide ready-to-use Python script
   # Just configure armor combinations in JSON:
   {

     "helmet": "bronze_helmet.glb",
     "chest": "bronze_chest.glb",
