Welcome to Lesson 3! Now that you have your Unity project set up and version control in place, it's time to establish a professional art pipeline that will support your entire RPG development journey. This lesson will transform you from a beginner into someone who can create and organize game assets like a pro.

What You'll Learn

In this lesson, you'll master the art pipeline fundamentals that professional game studios use:

• Art Style Definition - Choose a cohesive visual style for your RPG
• Asset Organization - Create a professional folder structure
• Blender Setup - Configure Blender for game development
• 3D Modeling Basics - Create your first game-ready 3D model
• Asset Pipeline - Streamline the workflow from creation to game

Why This Matters

A solid art pipeline is the foundation of every successful game. Without proper organization and workflow, you'll spend more time searching for files than creating content. By the end of this lesson, you'll have a system that scales from solo development to team collaboration.

Step 1: Define Your Art Style

Before creating any assets, you need a clear visual direction. This prevents inconsistent art and saves countless hours of rework.

Art Style Options for RPG Games

1. Stylized Fantasy (Recommended for Beginners)

• Characteristics: Exaggerated proportions, bright colors, simplified details
• Examples: World of Warcraft, Genshin Impact
• Benefits: Forgiving for beginners, AI tools work well, distinctive look
• Tools: Blender, Substance Painter, AI image generators

2. Realistic Fantasy

• Characteristics: Human proportions, detailed textures, realistic lighting
• Examples: The Witcher 3, Skyrim
• Benefits: Immersive, professional look
• Challenges: Requires advanced skills, longer development time

3. Pixel Art/Retro

• Characteristics: Low resolution, limited colors, nostalgic feel
• Examples: Stardew Valley, Undertale
• Benefits: Unique aesthetic, faster to create
• Tools: Aseprite, Photoshop, AI pixel art generators

Mini-Challenge: Art Style Decision

Create a mood board for your RPG art style:

1. Research Phase (15 minutes):

   • Browse games with art styles you admire
   • Save 10-15 reference images
   • Note what makes each style appealing

2. Decision Matrix:

   • Skill Level: What can you realistically create?
   • Time Investment: How much time per asset?
   • AI Integration: Which style works best with AI tools?
   • Target Audience: What appeals to your players?

3. Document Your Choice:

   • Write a 1-paragraph art style guide
   • Define color palette (3-5 main colors)
   • Set character proportions (realistic vs stylized)
   • Choose texture style (hand-painted vs realistic)

Step 2: Set Up Your Asset Organization System

Professional game development requires military-level organization. Here's the system that scales from indie to AAA.

Unity Project Folder Structure

Create this folder structure in your Unity project:

Assets/
├── 01_Art/
│   ├── Characters/
│   │   ├── Models/
│   │   ├── Textures/
│   │   ├── Animations/
│   │   └── Materials/
│   ├── Environment/
│   │   ├── Models/
│   │   ├── Textures/
│   │   └── Materials/
│   ├── UI/
│   │   ├── Icons/
│   │   ├── Buttons/
│   │   └── Backgrounds/
│   └── Effects/
│       ├── Particles/
│       └── Shaders/
├── 02_Code/
│   ├── Scripts/
│   ├── Prefabs/
│   └── Scenes/
├── 03_Audio/
│   ├── Music/
│   ├── SFX/
│   └── Voice/
└── 04_AI_Generated/
    ├── Text_Content/
    ├── Images/
    └── Audio/

Naming Conventions

File Naming Rules:

• Format: Category_Type_Name_Version.extension
• Examples:
  • CHR_Hero_Warrior_v01.fbx
  • ENV_Tree_Oak_v02.fbx
  • UI_Button_MainMenu_v01.png

Material Naming:

• Format: M_Type_Name
• Examples: M_Character_Hero, M_Environment_Stone

Pro Tip: Version Control for Artists

Even if you're not a programmer, version control saves your art:

# Commit your art assets regularly
git add Assets/01_Art/
git commit -m "Add hero character model and textures"
git push origin main

Step 3: Install and Configure Blender

Blender is the industry-standard free 3D software. Let's set it up for game development.

Download and Install Blender

1. Download Blender 4.0+ from blender.org
2. Install with default settings
3. Launch Blender and create a new project

Essential Blender Add-ons for Game Development

Enable these add-ons in Blender:

1. Go to Edit > Preferences > Add-ons
2. Search and enable:
   • Node Wrangler (essential for materials)
   • Rigify (character rigging)
   • Import-Export: FBX (Unity compatibility)
   • Import-Export: glTF 2.0 (modern game format)

Blender Interface Setup

Configure your workspace for game development:

1. Switch to "Modeling" workspace
2. Set up viewport shading to "Material Preview"
3. Enable "X-Ray" mode for easier modeling
4. Set units to "Metric" (Edit > Preferences > Scene)

Essential Blender Shortcuts

Master these shortcuts to work 10x faster:

• G - Grab/Move
• R - Rotate
• S - Scale
• Tab - Toggle Edit/Object mode
• Ctrl+Z - Undo
• Shift+A - Add menu
• Ctrl+Shift+Alt+C - Set origin to geometry

Step 4: Create Your First Game Asset

Let's create a simple sword that demonstrates the complete pipeline from Blender to Unity.

Step 4.1: Model the Sword

1. Start with a cube (Shift+A > Mesh > Cube)
2. Enter Edit mode (Tab)
3. Scale the cube (S + Z, then drag down to make it thinner)
4. Extrude the blade (E + Z, then scale)
5. Add a guard (E + X, then scale)
6. Create the handle (E + Z, then scale)

Step 4.2: UV Unwrap for Texturing

1. Select all faces (A)
2. Mark seams (Ctrl+E > Mark Seam)
3. Unwrap (U > Unwrap)
4. Check UV layout (Switch to UV Editing workspace)

Step 4.3: Create Materials

1. Switch to Shading workspace
2. Add a new material (click "New" in material properties)
3. Name it "M_Sword_Steel"
4. Set base color to a steel gray
5. Add metallic and roughness values

Step 4.4: Export to Unity

1. Select your sword object
2. File > Export > FBX
3. Settings:
   • Scale: 1.0
   • Forward: -Z Forward
   • Up: Y Up
   • Apply Modifiers: ✓
4. Save as WPN_Sword_Basic_v01.fbx

Step 5: Import and Test in Unity

Now let's bring your creation into Unity and make it game-ready.

Import Settings

1. Drag your FBX into Unity
2. Select the imported model
3. Configure import settings:
   • Scale Factor: 1
   • Mesh Compression: Off (for now)
   • Generate Colliders: ✓ (for physics)
   • Generate Lightmap UVs: ✓

Create a Prefab

1. Drag the sword from Project to Scene
2. Position it (0, 0, 0)
3. Create a prefab (drag from scene to Project)
4. Name it "PREFAB_Sword_Basic"

Test Your Asset

1. Add a simple script to make it rotate:

using UnityEngine;

public class RotatingSword : MonoBehaviour
{
    public float rotationSpeed = 50f;

    void Update()
    {
        transform.Rotate(0, rotationSpeed * Time.deltaTime, 0);
    }
}

2. Attach the script to your sword
3. Press Play and watch it spin!

Step 6: Establish Your AI Integration Pipeline

Since this is an AI-powered RPG, let's set up systems for AI-generated content.

AI Image Generation Workflow

For Concept Art:

1. Use Midjourney/DALL-E for initial concepts
2. Generate multiple variations
3. Select best concepts for 3D modeling
4. Store in Assets/04_AI_Generated/Images/

For Textures:

1. Generate base textures with AI
2. Import to Unity as materials
3. Apply to 3D models
4. Refine in Blender if needed

AI Text Content Integration

For Item Descriptions:

1. Generate item lore with ChatGPT
2. Store in Assets/04_AI_Generated/Text_Content/
3. Create scriptable objects for easy management
4. Integrate with game systems

Common Mistakes to Avoid

Mistake 1: Inconsistent Naming

# Wrong - confusing and unprofessional
sword.fbx
Sword_Model.fbx
sword_v2.fbx

# Correct - clear and systematic
WPN_Sword_Basic_v01.fbx
WPN_Sword_Enchanted_v01.fbx
WPN_Sword_Legendary_v01.fbx

Mistake 2: Wrong Export Settings

• Scale issues: Always check scale factor
• Axis problems: Use -Z Forward, Y Up for Unity
• Missing materials: Ensure materials are included in export

Mistake 3: No Version Control

• Lost work: Commit art assets regularly
• No backup: Use Git for all project files
• Team conflicts: Communicate about file changes

Pro Tips for Success

Tip 1: Start Simple, Scale Up

• Begin with basic shapes (cubes, spheres, cylinders)
• Master simple assets before complex characters
• Build your skills gradually

Tip 2: Use Reference Images

• Collect reference images for every asset
• Study real-world objects for accuracy
• Create mood boards for consistency

Tip 3: Optimize for Performance

• Keep polygon counts reasonable (under 10k for characters)
• Use texture atlases for small objects
• Test performance in Unity regularly

Tip 4: Document Everything

• Create style guides for your art
• Document your pipeline for team members
• Keep notes on what works and what doesn't

Troubleshooting

Problem: Model appears too small/large in Unity

Solution: Check import scale settings and Blender export scale

Problem: Materials don't appear in Unity

Solution: Ensure materials are included in FBX export and check material names

Problem: Model has weird lighting

Solution: Check normals are facing outward and UV mapping is correct

Problem: Performance issues with many assets

Solution: Use LOD (Level of Detail) groups and texture compression

What's Next?

Congratulations! You've established a professional art pipeline that will support your entire RPG development. You now understand:

1. How to define art style for consistency
2. Professional asset organization that scales
3. Blender setup for game development
